You can try dialing back the "hardware acceleration" on your video
adapter. (Display Properties, Settings, Advanced, Troubleshoot, move the
slider incrementally left, Apply, and then test)

I have the strangest problem. It doesn't happen all the time, but enough to
be aggravating! I have Excel 2003 SP2 on Windows XP SP2. I notice it mostly
when I'm going back and fourth between two or three Excel workbooks, but I
don't have a lot of applications open (like today, I had Outlook, a Windows
Explorer folder, and 2 Excel applications open - each had 1 workbook open,
both workbooks were simple, one tab with data, some formulas, but nothing
complex, mostly "sum", and not even enough data to have to scroll down the
page). If I bounce back and fourth - like between workbooks - sometimes the
data on my workbook will pretty much disappear. You can see the cell
outlines, but the content is gone. If I page up and down, the data comes
back. It's not actually deleted, it just looks like it is. Today it happened
when I was copying roughly 15 - 20 cells. I highlighted the cells and right
clicked on them to get the shortcut menu - most of the data on my workbook
blanked out. It will stay that way until I page up and down. Sometimes it
comes back if I use the mouse to scroll up and down, but it always comes back
if I use the page up and down keys.

I've had my computer checked, thinking it's a memory issue, but everything
looks fine. I've checked the memory available and used within Excel, but it
all looks good. It doesn't happen all the time, but when I'm working with my
workbooks it does turn into an inconvenience having to page up and down.

Has anyone seen anything like this before?
