A coworker asked me for help with excell (2003). While working in a
spreadsheet, her mouse would not respond. I looked at it and saw a CD ROM
icon next to the mouse icon, and in fact, it would not move. I hit
ctrl-alt-del and the task manager popped up, and I was able to use the mouse.
I then canceled the task manager and it took me back to the spreadsheet
where the mouse had a normal icon and was functioning properly. Any ideas
why this might have happened and how it can be prevented in the future.

Thanks as always,
