Same thing happening here with two different users. It happened to me
running a single instance of Excel and another operating the same way. Excel
2007 SP1 with 1GB RAM on one box and 1.5GB on the other.

Both boxes are update with OS patches and completed a repair on both.

Still occurs 1-2x/day.

When our heavy Excel user has five or more instances of Excel open, usually,
the display begins to fail. It's as if each sheet were composed of tiles and
the tiles were randomly moved around. Also, the programs no longer respond to
mouse clicks or keystrokes.

I disabled all graphic features to no avail; no entries in the Event logs.

Thanks for any help.
