I have a strange issue on a Windows XP Media edition PC. There are 2 users that can log onto the PC but one of them gets what appears to be mssing pixels in a line on his desktop. ONLY on his desktop, you can drag a window over the area and there is no line on the window.
I've tried changing the wallpaper thinking it was part of the wallpaper, but no luck. If you scroll your mouse over the area it highlights, but there is no action that can be performed (i.e. right click and delete).
I asked the person who owns the PC to uninstall the video card and reinstall it since it appears that it's not monitor related. haven't heard the results yet.
Thanks in advance
