Problem with the taskbar not recognizing the mouse

After updating my Windows 8.1 today (KB2919355 and KB2933809), I realized that the taskbar sometimes doesn't recognize the mouse when it is at the very bottom pixels of the screen. I have yet to find a pattern to when it happens, but I just tested that it always happens when I switch to something that opens in full screen in the taskbar, go in the opened window and then go back down into the taskbar. It can get really annoying when you are often going from one program to another. I use start8 if that can influence it any way but I don't think that is the reason. Thanks for your help!

Edit: Not only programs in full screen it seems.

Hello Spinatbaum, and welcome to Eight Forums.

If you mean while in a modern app or screen, I find that pressing the :winkey: + T keys work best to open the taskbar with.

Hope this helps,
Shawn
