Recently (as of 10/2/2010 on Windows 7 x64) When I have multiple windows open, whenever I click on a different open application on the taskbar instead of the window popping up, the item on the taskbar just blinks orange. (This is the same "blinking" that occurs when something has changed on an undisplayed window.)
The only way to see the window is to hit "show desktop" and re-click on the taskbar item. (I should note that the item then becomes solid-orange until I open it.)
Even Alt+tab does not do a thing! (However, 3D Aero switching *does* work)
Still, this is obviously a major nuisance. I am very computer-savy, so I have searched registry items suggested by other forums/questions; however, I cannot find the issue. Oh, and I cannot find any particular software I installed prior to seeing this issue.
Please help! This is obviously a MAJOR hindrance to me. (I am a software engineer who usually switches between many applications...) Thanks in advance!
