When i am closing firefox or safari sometimes it leaves blurred remnants of the last image on the screen. If i click and make a window around the remnants irt will disapear but i am worried that maybe my video card is going. Anyone else have this problem?
thanks

Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when complete, test again.
Get Temperature Monitor to see if it's heat related...

If you have any temps in the 70°C/160°F range, that's likely it.

You can avoid image persistence in a couple of different ways.
see > Avoiding image persistence on Apple LCD displays
I never see image burn or persistence because I move things around a lot while working and have my display set to sleep after 5 minutes of inactivaty.
I also think it helps to use dark or abstract desktop images.
