I tried to update the video drivers on my IBM thinkpad t42 but now there is a white line around my windows. It is a small white line about 1 pixel wide. The line appears when I open a new windows or change tabs in a window. If I click on the line it will disappear. When I tried to take a screen shot of the line it disappeared. XVidCap does not show the white line either. The white line only appears when windows are full screened.
