I have dual monitors on Office 2007 and Windows XP Pro. At least once a day
Excel goes crazy. I'll have Excel up on one screen with either other office
applications on the other screen or another instance of Excel. All of a
sudden, my ribbion will go black. The spreadsheet itself will split with the
top half on one monitor and the bottom half on the other. Or, perhaps both
monitors will just go gray. As I drag my mouse over where the ribbon should
be, buttons and icons will reappear allowing me to save the file.

This has happened at the beginning of the day, in the middle and at the end
of the day. It happens when I have no file up and when I have a number of
files up. It happens when I'm only running Excel and when I have a number of
systems working.

After getting out of Excel, bringing it back up and bringing up the file,
everything is fine. The file is not corrupted. Everyone in the office who
has multiscreens and works on Excel 2007 suffers this problem. Those who
have one
monitor, don't. This makes me believe it's a video card problem. Can you
suggest either a fix, patch or better video card I can instruct my IT teckies
to buy?
