taskbar is acting rather weird

hi every,

im running a vista premium, and recently ive noticed that my taskbar is
acting weird.
1 - the taskbar thumbnail preview works, but it doesnt minimize after i move
the mouse away from it
2 - there is a problem highlighting the current running windows (the blue
shadow highlighting). like for example, when i switch between windows using
the alt+tab, or when i switch manually, buy clicking on the window header
without clicking on the taskbar, the highlight remains on the previous
window...

please help!!!

This sounds like Video Drivers so I would look for an update.

Try turning AERO off to see if that solves your problem. You can
also turn Transparency Off as a check.
