Windows 7 full screen games and desktop applications losing focus and stealing discussion questions

NOTE: The updates at the top of this announcement, the original message is less than.

UPDATES: here are a few updates and new information that I have gained since the original publication.

Registry settings

After doing a lot of reading, I found some registry settings that appear to solve some of the problems I see. All three were found in HKEY_CURRENT_USER-> Panel-> Desktop

ForegroundLockTimeout: Has been reset for some reason any. I removed the key and restarted, but he is back to zero. This is why I looked at the default value of 200000 (decimal) and set it. After that, he stayed. \

I saw two other keys HungAppTimeout, WaitToKillServiceTimeout, and WaitToKillAppTimeout and all have been set to zero. I deleted these registered.

I have no idea what set these registry keys to zero, but after being put into default, I can now click on an application full screen reduced, and he returned immediately. I can still lose focus in full screen or desktop app, but not as often as before and now he is usually just badly behaved apps stealing focus rather than seemingly random events.

I wonder if there is a patch that has changed these values, or a settings option that does. From what I read, they are sometimes twisted to allow faster restart and stop servers.  I don't have a software that would be while and manually set their and none have the people I know. One of them has confirmed that their box also has these set values zero and has no idea why.

I hope this information is useful to other people with odd focus problems.

ORIGINAL POST FOLLOWS *.

I have a problem in Windows 7, which at first I thought a number of different problems, but I am more convinced that they are all connected.

All of them started to happen around the same time - late January or February after a Windows Update - and largely the same or very similar issues affect 3 of my friends and co-workers running Vista and 7. Unfortunately my notes on the update happened while the time are missing, but all 4 of us have seen questions start at the beginning of the year in the January/February calendar, which makes it seem like they should be linked.

NOTE: There were a few minor problems before even with the update, but nothing like what happened in early 2011. I had problems to update with Vista and 7 alone, but they were rare and sometimes fixable with registry hacks or it was an offending program, something did not like Aero, etc..  The questions below got a lot worse in early 2011 so they appear together in this post.

I will describe each problem separately and the affected BONE and the symptoms, and I hope that some can make sense and help me solve the problem. Major problems first, then a few small problems and measures that I took to the to check follow after. Sorry for the long post, but it's a maddening problem affecting many people, and I want to be as complete as possible.

Games not switching and the apps full screen #1: if I'm in a game fullscreen and I go to the office, it is very difficult to go back. If I click on the taskbar icon, nothing happens. I have to click on it repeatedly, often a dozen times or more before the application full screen or game is restored. It is most often with the games. Full screen I don't want not maximized, I mean where a program takes the entire screen. Games is easier to reproduce so far have all I currently use the question and variances in how it is difficult to come back in full screen are not significant between them.

Apps full screen #2 focus lost: this happens especially to my friend running Vista, when you play the game full screen. She will play something like the Lord of the Rings Online and she loses the keyboard focus and the mouse, but the game is always full screen. Usually the only way that she can solve the problem is to use CTRL-ALT-DEL to bring up the Task Manager, which for some reason solves the problem and she can return to the game for a little while that. I run Windows 7 with another couple of friends and we can also see this question, it is much less common. Changing an old mouse seems correct for Vista for some reason any. 7 that it happens rarely, if hard to duplicate to see if changing the mouse would help. In any case, will and against a beautiful new mouse laser mouse is usually a horrible option.

Office applications #3 lose focus: it affects two of us under Vista and 7. We will be typing in chat, email, anything... and the foreground app will lose focus. What catches there that is impossible to determine. In my case, I can occasionally see a taskbar popup button and then disappear immediately, but I have never been able to track it down. Running in safe mode or boot seems to have no effect on this, or disable all services, extension and program but by default Microsoft in Windows 7 and Vista. Its almost like a Microsoft program is to do. Also, even though I mentioned the taskbar icon appears briefly from time to time, which cannot be bound: it does not always coincide with the loss of focus and is not always present when the focus is lost.

#4 desktop applications lose keyboard focus and the mouse: it's like the number #2 above, but happens at the level of the office. Unlike the #3 that the window does not lose focus, it is always in the foreground, but keyboard and mouse stop working. It is usually impossible to move to another window. Just like #2, the solution that we have so far is to use CTRL-ALT-DEL to switch to the Task Manager, which temporarily solves the problem. ALT-tab through windows does not work.

Here are other minor problems that may or may be linked, because they seemed too much to start with.

Switching away applications full screen takes more time: Windows 7 on my machine, switching off games full screen takes more time than he did in the past. It was a minor issue in autumn 2010 and became much worse early 2011.

Some windows lost focus while being re-size: if I take the corner of some windows for re - size, sometimes the re-size operation stops until I release the mouse button, as if he has lost the focus. Color of the window indicates usually focus however is still there, and grabbing the corner once again we will move me a little more. It may take several tries to get the window size as I want, as the re-size operation closes several times before I release the mouse button. This affects only 2 of the 4 people I talk so much that I can tell from our conversations and shared between Vista and 7. Both of us have Logitech mouse it might even be a driver problem, but using a mouse cheap test has not fixed the problem with me.

Firefox: Firefox repeatedly will "dim", where Aero makes the window lose color to indicate that the application is not responding. It didn't happen before January 2011 for any version of Firefox.

Concrete results to track down the problem:

I ran programs like WhatHang and others who are trying to catch the programs that are suspended, stealing focus, etc.. Hours of testing found no results except that Firefox crashes frequently. Disable Firefox doesn't solve all the issues however, so I guess that its not related.

I tried booting safe and clean, and they have had no effect. Secure boot is rather useless since I can not usually run programs that show the problem more easily. I also tried turning off everything except what comes with Windows 7, and it had no significant effect.

I tried to use a different mouse. While it helped a bit with one of my friends, it only helped me so far. Different mouse drivers do not seem to help either. I also tried various nVidia without significant information acquired or corrective drivers.

I also ran through various other ideas here as the race of the file system scanner and so on and not found any problems with my system, and where I could help my friends do and they also found nothing of note with maintenance and verification tools.

My friends and co-workers: most of them are not local to me, so my focus of their issue has been rather limited. The main thing that we all have in common is that we had some minor problems in the past, as in 2010, and they've all got a lot worse in early 2011. Unfortunately none of us kept of records accurate enough to indicate any special updates that might have caused it.

In any case, I apologize for the log message, but this issue emphasis is maddening. Its become a frustration serious then I thought to post information on the problems which seem related would be the more useful approach.

I am a graduate of comp-sci systems and a companion systems programmer, and I have tried everything I can think of to debug and isolate problems, symptoms, etc. and had no chance. My friends are usually illiterate computer so that they are even more perplexed and frustrated by this problem. In my reading the forums, I see a lot of Windows Vista and 7 discussion questions, but rarely a lot of details, and when a problem is identified, it this far does not apply to me or my friends.

I am happy to provide any other details I can.

Updates:

I forgot to mention that I have a Setup dual monitor. Aero seems unhappy with it, a lot of flicker when switching to full screen in games and other applications. I guess its because a single display off Aero while the other has it we or maybe not accelerated. Remove the second screen does not solve the problems I see, but I mention it in the interest of further development.

I want to just chime in that I see similar (but not exactly the same) behavior and time seems to match as well. Among the updates must have messed something up. I forgot my Cardinal never update rule anything :/

In any case, I have a few specific questions all problems related to full screen/window/input. When you play the Witcher, when you look at, if the mouse touches the edge of the screen, it stops, thus giving a very narrow range of angles I can watch from. Baldurs gate, as soon as I hit any key, I can't click on anything whether (and what I typed does not appear). Looking for police 3 (dosbox) it works fine until I hit a key, and then the mouse bounces oddly around the screen. If I alt - tab, in these 2 cases to last and go back, the problem is solved until I have a button again. In the case of the Witcher, if I alt tab and click the icon to the taskbar, it seems this problem, until I have a press.

And I'm sure I had none of these problems a few months ago. I have tried everything I can think :( I tried the registry settings, but they do not seem to help.

Edit: Oh, almost forgot. Whenever I click on full screen on an online video, like youtube, it appears in the background behind other windows, and then I have to click on it in the background to bring it forward. Very weird. Not sure if it's related. I'll try to change my video drivers... So boring when everything was working fine a few months ago.

Edit 2: Do not take into account my post, I had a program called synergy race (usually use a mouse on multiple computers at the same time). Apparently, he was the problem.

  • How to get Skype calls to overlay full-screen games in windows 10

    Hi.Here is my problem: in Windows 10, while I'm in a game session full screen, if someone calls me on Skype, instead of a small window centered to answer the call on the current game I get a black screen. In windows 7, it wasn't the case, I could just answer of in the game, just by clicking on the small window that overlayied the game and continue playing happily. I know that it's more a problem of Windows 10, but if we could get Skype to work stacking game would be nice, especially since a black screen on you the current game session is very dissruptive.

    Well, I tried anyway, but I don't think it could be fixed, because in windows10 any notifications get you a black screen, in some cases, it crashes the game (all within a game fullscreen).

    F takes you on a full-screen, is just "lights out" so you see what is currently in front of you, but without the panels. D and G switch between the library module and to the point, but as soon as you press those then you exit the full screen.

  • Scroll the VerticalFieldManger to see the full content of the message without losing focus on the AutoTextEditField

    I create the application such as chat window.

    I used VerticalFieldManager, AutoTextEditField and RichTextField.

    AutoTextEditField - tap the message.

    RichTextField - add the chat messages

    RichTextField is add in VerticalFieldManager.

    How to scroll the VerticalFieldManger to see the full content of the message without losing focus on the AutoTextEditField.

    Override navigationmovement. This is example how im using it.

    protected boolean navigationMovement(int dx, int dy, int status, int time)
     {
      if (dy==1)
        {
    
      int newscroll = mains.getVerticalScroll();
      int pageheigh = mains.getHeight();
        mains.setVerticalScroll(newscroll+50);
        invalidate();
      return true;  }
    
    return super.navigationMovement(dx, dy, status, time);}
    

    50. This is the step. This is very good work for me (but must create if newscroll <0 and="" if="" newscroll="">the field of cat yourmanager)

    area = VerticalFieldManager()

    Hope this makes you help.

  • My games is displayed in a small window, not full-screen.

    I installed a game for learning since 1996 and when I try to play a game like Grand Theft Auto IV it is displayed in a small window like the 96 set appears. How to restore mode full screen in my games?


    Once the game started, click Options, then check that full screen is selected.  If this does not produce the correct results, right click on the file *.exe to the game on your desktop (Yes, you will need to do this for ALL of your games that are not correct) and select Properties, then in the shortcut tab, verify that, in the Fun section, Normal or enlarged Windows is selected (the one that produces the desired result).

  • Machine virtual Windows 7 - freezes\reverts of the screen when going from Windowed to full screen and vice versa.

    I use a Win7 box with a Machine virtual Win7 on it.  When I started using the VM, it should start and login and work very well.  Shortly after I started having the following problem.  It loads in windowed mode, so I me the welcome greenish\blueish after cutting inside.  If I wait for the Office to load, when I do the full VM screen, it goes full screen then the screen goes to the Welcome screen again, but it's just a static image.  It won't change until I have send a Ctrl-Alt-Del command.  Can I get the normal window with options for logging, start the Task Manager, etc..  If I press ESC or click Cancel, it will show the office and I can work on it without problem.

    If I leave full screen mode windowed after that, the same thing happens, except instead of the Welcome screen, I get the screen of Ctl-Alt-Del as a static picture.  Once again, if I send the Ctrl-Alt-Del command, then cancel, I get the office as usual and it will work until I have try to resize the screen again.

    Can someone help me understand what is happening?

    Thanks in advance,
