Whenever I either open a current spreadsheet or use a new spreadsheet, if
you click in any of the cells, it shows a box around the cell, and a blue
area as if you were selecting and copying that cell and others in the
immediate area.

The problem is that I can't escape out of that, nor can I select anything
else or use Excel at all.

This happens with both new and old worksheets, and the only way out of it is
to ctr-alt-delete to close down the program.

I have rebooted several times, as well as checked to make sure office was
completely updated, and it's still doing the same thing.

I am using Office XP Professional 2002.

Anyone got any ideas on what I should do short of uninstalling and
reinstalling Excel?
