I seem to have set Excel 2003 to a particular cell selection mode that I can't
seem to turn off. My cursor is the big plus sign and when I click on any cell
in a spreadsheet - existing files or even an empty spreadsheet - the selection
mode stays active and no matter where I mouse to, the selection keeps expanding.
No click, right-click, shift-click, alt-click, or any keyboard command I could
think of turns this off. Nothing in the menus seems appropriate, and I can't
seem to find anything in the online help on this issue, so I'm obviously
confusing some terminology. I would be very grateful for some advice. Thanks!
