    Strange behavior from taskbar-cursor interaction?


    My tale of woe can be seen here: No taskbar with a maximized Firefox screen? mozillaZine Forums . Up until a few days ago, whenever my cursor hovered at the very bottom of the screen, the taskbar would appear. And, when the cursor was moved away from the bottom, the taskbar would disappear. My Windows 10 setting was to automatically hide the taskbar. Now, however, the taskbar would obey the cursor when when first booting up the computer, but would then revert back to not bringing up the taskbar after some links were used, or a new app opened (like Thunderbird.) Once the taskbar no longer worked right, it could be rejuvenated by F11, but this only lasted for few minutes before the taskbar would stop responding.

    And now I am noticing an interesting process that causes the taskbar/cursor interaction to fail. I have Firefox open and Thunderbird minimize, with the taskbar working. However, if I merely place the cursor on Thunderbird's icon on the taskbar, the taskbar becomes hidden and can't be viewed. Same thing happens with any other program that has been opened and has been minimized to the taskbar. The only way I now can be sure to see my taskbar is to use Window settings is to have "Automatically hide taskbar in desktop mode" set to Off instead of On...the On setting was working for years...

    EDIT: The only program that I put on lately was Kodi 17.1. I haven't removed it to test this as I don't want to go through resetting it up.

    :)

    Hello!

    Thank you for the answer.

    At the same time i checked Windows log:

    attemping to call lmb click causes application messages:

    Activation of app Microsoft.Windows.ShellExperienceHost_***!App failed with error: Invalid value for registry See the Microsoft-Windows-TWinUI/Operational log for additional information.

    This thing helped resolve described problems

    • Open an Elevated Powershell prompt by pressing the Windows Key, typing Powershell, then pressing Ctrl+Shift+Enter
    • Paste the following command into Powershell and execute it:

      Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

  4. Strange behavior from taskbar-cursor interaction?

    Ive heard some stories of where Windows 10 for some reason seems to get confused as to whether a device is a desktop or a laptop/tablet. Im going to suggest trying this:

    Go into your settings, instead of going to where the taskbar settings are, open settings and go under system. Select Tablet mode.

    See that your settings look like this. "When I sign in" is set to desktop mode, "When this devices switches..." is set to dont ask and dont switch. This is what I would try. See if that works for you.

    I'm having this same problem, so I too would like to fix this!

    I followed your advice and if the open windows are full screen the taskbar doesn't show but if I reduce the window size and move it away from the taskbar the taskbar then shows and hides correctly. So full screen seems to be the problem now. I'm on a laptop, by the way.

    Thanks.

    Agreed, could have something to do with "full screen."

    Arezal, tried your suggestion. Seemed to work when in Firefox open screen, but as soon as I placed the cursor on the minimized Thunderbird icon, the taskbar disappeared and wouldn't reappear with cursor hover???

    Strange behavior from taskbar-cursor interaction?

    Now there's a funny thing.

    My problem seems to have gone away! I can use Cyberfox and Waterfox with full screens, along with the rest of my apps on the taskbar.

    What have I done? Two things, I was looking at how to revert back to previous build (under Recovery) but it told me that I couldn't use it as my UAC settings wouldn't allow it. So I changed the settings to see what would allow Recovery, I originally had the 'topmost' setting, which blocked Recovery but when I took it down to the second position I can now use Recovery.

    The other thing I did, I spent the afternoon gardening! Came back onto the laptop and the taskbar was behaving correctly.

    So, was it the UAC setting, as that is the only thing I changed?

    Answers on a postcard please.*Smile

    i usually see this problem when an application is forcing itself to be on the forefront at all times of the desktop over the taskbar itself.
