    I have 9, 1 pages in PDF files that are accessible and the need to combine them into 1 PDF file.  I tried adding, adding and the combine process of PDF files. The file created does not take my changes. The file created is partially accessible, but I have to re - the problems that I had fixed in the unique files. I need suggestions on what else can be done, if any. Using Acrobat pro XI.

    By habit, I tend to combine PDF files in the Page pane by right-clicking thumbnails then 'Insert of Pages'-> 'From File'. For me, this preserves the tags of these two documents, although the tags may have to be moved to the correct location (if I remember correctly the tags for inserted pages are put at the end of the tag structure, regardless of where the pages are inserted), if I put the tags in the document to insert into a container as a Section tag It makes the process easier. Travel set of tags in the right place is the only re-fixing that I remember having to do. What behavior you encounter?

  • I can't turn off my touchpad of Hp, disable it in usual way does not work.

    Hi guys, I can't turn off my touchpad of Hp. the normal procedure of closing does not work. I bought 5 days back. It's a button up, once, I continue to pressing power, it displays the function stop, I tried more than 10 times. the stop screen pop-up does not appear.

    You can also press the up arrow in the lower right to open the Launcher to do stop (you need before you start a reinstallation). Once it opens, go to the settings tab. Click to open "device Info". At the bottom of the window, click to open 'Reset Options'. 'Close' should be the second choice there. I hope it will work for you.

  • Firefox loads, icon on the bar of tasks but when you click the slide of graphics off to the right, but does not fill the screen & when you right-click again, falls back into the icon

    Firefox, Thunderbird and Quicken were active when I loadad & ran a slot machine game. When I left the game & click on icon to return to Firefox full screen, I could see the flash of the image to the right of my screen and disappear. When I clicked on the icon in the taskbar, the reverse happened - the image flashed from the right down to the icon. When I hover the mouse over the icon, the open screens appear with the red X to close, but the same thing happens when I click on this box. Two other programs that have been opened, while the game was active work correctly, only Firefox has been affected. I can't open the program to access one of the menu items that I can't get the image of the screen on the monitor. I did uninstall and reinstall a freshly downloaded copy, I had to use IE, as I am now) but with the same results when I run. I did chose to save my settings, so if something has changed here so maybe that's the problem.

    Hello

    Try Firefox Safe mode to see if the problem goes away. Safe mode is a troubleshooting mode, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open Firefox 4.0 + in Safe Mode holding the key SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. It might help others who have the same problem.

    Thank you.

  • Button value change records in the structure of the event, but does not change appeaance?

    Hello world

    A quick question... I hope someone can answer...

    I have a code that uses a PS button within a structure of event to trigger a signal of AO... My code is below. The code works fine and the OD goes off when you press the button E-Stim... But when pushed the button does not change with reliability the appearance (i.e. of the gray 'off' red 'on' color)... Sometimes color changes; no other time not... If I remove the structure of the event and the survey button in the appearance changes as expected.

    What is going on? I would like the button to change the colors on the user interface to indicate that it works... Should I programmatically control the color?

    Kind regards

    Jack

    I guess that when query you the button you have some delay in your loop? Locking means that the button will change its value when you press it, then switch back to the original value once the value of the control has been used by the code. When you ask, this means that until he reaches the next iteration of the loop, but in the case where the structure that will happen immediately.

    The default setting for the buttons to modify its behavior as in most of the application would be latch releasing. You then raise the event when the button of the mouse over the control. This also allows "drag" control if you push down on the subject, given that you do not release control in this case.

  • Equium A20 fell and the screen turns off always

    Hi, I was using my satellite A20 long (4 years). Never had any problems. Recently he fell and the screen turns off always.

    I can see the toshiba logo and the windows logo also when starting, and even I can enter the BIOS and change the boot order too... but as soon as windows load screen is black. I don't understand

    Anyone with the solution?

    Thanks in advance...

    Hello

    > but as soon as windows load screen is black. I can t understand
    This means that the display output has accidentally changed to an external.

    Have you checked if something would be visible on the second external monitor?
    Select this check box.

    In addition I advise to use the FN + F5 keys to check if you can switch the output back to the internal display.

  • Satellite 1800 - 752S - the screen turns off

    Hello world.
    I have a satellite 1800 - 752S.
    Since an ew months ithas a weird problem: the screen turns off. If I press and release the button the lid on what it is, but after that turns off again quickly. OT goes off sometimes immediately, sometimes after a few minutes, or even hours. Sometimes it provides be when I run out of battery and bothers me on AC, sometimes against. It works fine, after I turn sleep or hibernation several times, and after a reboot, it bothers me. I've updated his BIOS for the lates on this site, which would not help. I guess it's a hardware problem, because it's the same problem under Linux, and I tried to install different versions of drivers and windows (not only the one of the recovery CD). Anyone have the same problem before. Any help will be appreciated.
    Thank you very much
    Roman

    Hello

    I think you're right, it's a hardware problem. But to be sure, try connecting an external monitor. If it works without problem while laptops, screen turns off, then it must be a hardware failure.

    I guess it's a problem with the FL inverter. You have to give your machine a service partner Toshiba for repair.

    Good bye

    I checked power options, the first thing, and then I checked the (NVIDIA) graphics card Control Panel to see if there is a setting for it.  The figures that I had in my previous post came from my power options, but I don't know how standard power who do not have the numbers that it would affect the schedule/performance options.  I went to advanced settings.  But I also rebooted my computer which solved the problem, in my opinion.  I'll have to sit and wait to be sure, but I'll get back to you on that once I have test.
