Mail keeps opening unprovoked window

Since updating to OS X 10.11, my window of Mail keeps opening without rhyme or reason.

Mail is launched, but its window is closed, then at seemingly random times, the window opens suddenly, disrupt everything I was doing at the time. This also occurs when the Mac is in sleep mode, the window previously closed mail is open from wake up sleep. This is not related to any activity within e-mail, such as new audits of email arriving, periodic new email, synchronization status of e-mail with other devices, etc.

Everyone knows the same problem?

Is there a specific .plist file that I should try to remove?

Thank you.

User for messages settings are in the user's library > folder of containers:

~/Library/containers/com. Apple.mail

If you want to experiment with: Mail to quit.

Move the folder to the trash. Open Mail. You have to re-create your settings. You can always reverse this order in case of problems or to reset your original settings.

  • pop up problem, keep opening as window!


    My problem is that all my links keep opening as pop ups, I used the connection to the link buttons (arrow) button to the files (html pages), I did it on each page, its really annoying hope, someone can help me out as soon as possible, im using CS4!

    You have probably set up to open in a new page. That is why they keep it.

    When you add a link on your property bar, make sure that the 'target' is set to 'home' or the box must be empty. This way the links open in the same window without having to open a new one.

  • Yosemite MAC, when I open Firefox I get two windows, when I click on a link in mail, it opens a window not a tab.

    I place the FireFox icon in the dock. When I click to open FireFox it opens two windows both to the homepage. When you click on a link in the email, it will open a window behind the first window rather that open in a tab. There used to be a preference re: opening links, but given that it was useful, it seems that Apple has removed this option unless it's hidden somewhere I can't find.

    What you have is, in my view, two problems.

    • Homepage

    Type of topic: preferences #general< enter > in the address bar.

    There are two settings;

    • At the start of Firefox

    When the browser is started, what you want
    view. Many of us choose view my homepage.

    • Homepage

    When a new page opens up, what do you want displayed.

    1. Use current Page. Use the pages that are never open at this time.
    2. Use the bookmark
    3. Restore by default. topic: Home shows a home page of Mozilla with tools.

    You can use one of these as you want;

    topic: Home (Default Firefox homepage),
    on: newtab (displays the more visited sites),
    Subject: vacuum (a blank page),

    or you can enter any web page or Subject: page you want.

  • In the preview, is this normal for a series of small to keep opening browser windows?

    When I saw in the Internet Explorer browser, I receive a small string of the browser windows that I need to view my pages I have designed for maximized screen individually. Is this a standard DW Preview in the browser process? I use 4 DW and IE 7.  I have Vista OS with screen resolution 1600 x 1200. All the targets of my pages are fixed empty. I don't want myself or my viewers to be entered through this tedious process when the site is finally online. I have a problem here?

    You know, I get that every once in a while. I think it has more to do with how you last left your browser with something to do with Dreamweaver. Go to your browser, maximize, then shut up. Then open it again and see if it happens great this time.

    And, of course, you can't control what your viewers do with their browser, unless you create these behaviours 'display the new window '. Your behavior window was empty, maybe because you have to first select the thumbnail or text... and then in the behaviors panel, press the "add the behavior." Choose browser window open, etc. etc.

    I think I'm repeating myself

    Yes, those big arms can be pretty average... Let's see, it was a Charles Atlas ad in the back of comics, Yes?

  • How to keep each "open in Windows Mail file"?

    I use "Windows Mail" folders as a workbook.  But when I open or try to put something in a folder it opens and it takes forever to get to where I want to msg to go to.  Is there anyway I keep opening for 100% and just open the subfolder that I need?

    Why have they changed it in Outlook Express, that was such a good and well-organized program?

    Thanks in advance for the help!

    If you have 10 subfolders under one main folder, you do not see them all or none. It was the same in OE. If you want to 'post a message', expand the folder tree and drag the message into the folder wanted.
    Unless you make to each folder a subfolder of the folder above instead of the main folder, it should not take longer to get where you're going, regardless of the number of subfolders.

    It is relatively simple as you use and that you want to use WLM.

    You will need to copy a folder from where it is (the old installation) to another place where you know it will be (for example on your desktop)

    The folder is c:\users\your user name\app data (if it is not there, see the note below) \local\microsoft\

    At that point you will see a folder named oddly enough "windows live mail" copy on your desktop

    If you don't see the app data because it is invisible atm.  To make it visible, you need to go to your control panel > folder options > view > change to hidden folders (see figure)

    Once you have mail backed up on your desktop (or where ever) drag the folder from the desktop to the location for the new WLM (once again we C;-... just like above).  Just make sure that WLM does not run in time.  What wont be imported, it of passwords and rules.

    Accounts and data should now be in the new WLM when you open it.

  • If I click once on an e-mail in the message window while I closed the preview window, I opened that makes e-mail?

    If I click once on an e-mail in the message window while I closed the preview window, I opened that makes e-mail? I worry because I don't want to open a message that my bad-ware download on my computer. If the preview window is closed, I noticed that the number of e-mails read does not change when I click once on e-mail. Can I assume that unread means that it has not been opened.

    Read the answer! Your question is answered there.

    Read / unread is purely an indicator. It has no real meaning. If you go into the menu (alt + T) tools > options > advanced > reading and display, you can change when a mail is marked as read in immediately to 10 seconds (this is what outlook express used) up to 1000 seconds.

    The software marked the email read is that this logic can go. It's always "BOLD", the software did not mark the message read.

    You open the mail? It is an unquantifiable statement.

    In the context of Thunderbird an individual mail is not a discrete element that is stored. It is a part of your data for mail/News. So try to equate open to action just does not fit.

    Thunderbird received mail as a series of lines. He collected in an email that he stores in a file with all your other emails for this folder. You open the file in that the mail is stored? Totally irrelevant Thunderbird opens to get mail every time that mail is added to the folder or to view a mail in this folder.

    Each time a letter is displayed (any mail) the file all your emails for this folder are saved in the opening and reading.

    If clicking on the mail list 'open' the file. Probably not, it was probably already open. The file is opened, read, written to and updated probably half a dozen times since Thunderbird started so if you click on the mail to see won't change anything good at all. If the e-mail file has been closed it will be open to view the contents of the mail, but he is perhaps already open.

    The key is that you try to apply assumptions to mail that simply do not apply. That's why I sound as if I'm going in circles.

    You also may ask, when I fill the kerosene tank my electric light.

    • The software mark mail as read when you say
    • It opens files underlying storage constantly. Clicking on an entry may or may not cause the opening of the file.
    • Your mail is not in a file on its own, it is in a file that contains all the messages in the folder and the mail deleted until the folder is compacted.
  • I want to mail to open in a window

    I had to reinstall Thunderbird. But the new version of mail as a tab opens. As a tab in the browser. I want the mail to open as a new and separate, window as before. How can I change this back?

    In the Menu bar, select Tools-Options-advanced-reading and display

    No menu bar? Press the ALT key.
