Someone I work with has problems occasionally where Excel seems to be locked
in a cell selection mode. As he moves his cursor around, Excel selects a
range of cells as if he was holding down the shift key and selecting multiple
cells. I thought it might be his mouse, but that doesn't seem to be the
issue. Excel seems to be responsive, in general; we can select menu items,
right-click cells, etc., but it stays in that mode. He typically just
reboots to resolve the issue.

I've experienced this problem, but only rarely. I was thinking that I had
solved it by minimizing then maximizing the window, but that didn't seem to
help. Can anyone offer any suggestions?

Thanks,
Todd
