Data in cells not visible

[Michael Spratt]

I have a customer with several custom spreadsheets that he's developed
over the years. A few months ago, I replaced his two computers and
upgraded Office to 2007. He began to notice that some of his data
wasn't showing up in some cells. However, when he clicked on it, the
data would still be visible in the formula bar. This occurs on both
computers and on different spreadsheets.

The cells that appear empty are random. If he scrolls the spreadsheet
so the blank cells are no longer visible, then scrolls back, the data
reappears. It will also come back if excel is minimized and restored,
or if another windows is placed over blank cell and removed. He
discovered that the blank cells show up if he scrolls through the
spreadsheet too fast.

A couple of weeks ago, I replaced the video cards in his both his
computers to fix an unrelated issue. The blank cell problem persisted.
I replaced the onboard Intel video cards with ATI Radeon cards. The
Windows XP, all drivers and Office 2007 are completely updated. Any
ideas?

Does he use multiple monitors?

There have been some people who complained that the text would appear in the
formula bar, but not in the cell in the worksheet.

If no, then how about checking/fiddling with the acceleration settings for the
video card.
(that's a wild guess)

What happens if he changes to a different printer (or printer driver). Windows
uses the display and printer to determine what you see on the screen.
