I am running quite a bit of code behind my spread sheet and it all compiles
just fine with out any errors.

I have found that it crashes if I am switching between the spread sheet and
other programs. And often times it crashes when I return to the spread sheet
(not even running a macro) after editing code in the VBA editor. Sometimes I
never even open the VBA Editor and it crashes. This is very confusing and
frustrating.

This has only been an issue in Vista. I did not have any problems in
Windows XP.

Please help...
