Why is Excel undo list cleared when copy commaned used.

[Larry Dillard]

Excel 2003 was just installed on my machine. After a while of use, when the
undo list is cleared when I use the copy command, either by "ctrl-c" or right
click copy. Am I missing a setting?

Lots of macros kill that undo stack.

Any chance you have a macro running -- maybe even an event macro just lurking in
the background waiting for you to do something????

Does it happen on all workbooks, all worksheets?

Does it happen if you open excel in safe mode (macros are disabled):

Close excel
window start button|Run
excel /safe

file|open
(or just against the new workbook)
