One more piece of testing - I added a Command Button to one of the
sheets in the file and assigned the same "MyExit" macro to the new
button.

It works perfectly fine.

So - it is ONLY a problem when trying to run the code from a
commandbar button WITH other spreadsheets open.

I am sure I am not the only one to stumble accross this

BTW - I am running Excel 2003 if that makes a difference or helps at
all

Thanks.
