There are lots of things that can reset the undo/redo stacks.

You could have run a macro (or an event macro could have fired).

You could have saved the workbook.

There's a setting in the windows registry that tells excel how many undo levels
to keep track of--maybe it was set to 0.

My Excel 2003 undo and redo buttons (the icons and in the menu) are grayed
out and unavailable. What could cause that? How can I make the them active
again? This happens in both existing and new spreadsheets. Thanks.
