Taskbar window previews stay on the screen

[Guest Olivier]

Just recently I have this problem that the taskbar window previews don't go

away, even if I click on an application. The only thing that makes them go

away is to click on the start button and then somewhere else. It may have

started after I installed Explorer 8 but I also installed a bunch of updates

at the same time.

 

Is there a fix?

 

Thanks in advance
