I have my task bar placed at the top of the screen and auto-hide is OFF. This is what it normally looks like and should always look like
As you can see indicated by the red line, there is a space between my web browser and the task bar.
However if I restart my computer or if I open up a full screen game this is what happens:
As you can see the space disappears. I prefer the look with the space but the only way to get it back is move the taskbar back to the bottom, then move it back to the top. The space comes back if I do that.
However I should also mention that if I keep the taskbar on the bottom and turn off autohide, the space will be there as well but when I restart the computer the same problem occurs down there as well.
No idea what could be causing this, any ideas?
