I have an application I have written in which the first
step is to determine if a toolbar exists. If it does,
the macro makes it visible. If it doesn't, the macro
creates it and makes it visible. When the application
closes, it hides the toolbar. This all works well except
of the user quits the application without saving, Excel
crashes - every time. I have disabled the toolbar
portion of the application and the crashing goes away, so
I know it's in that area, but I don't understand why it
is causing the crashing.

Any ideas?
