It's really difficult to say what might be going on. It may be a problem
with the code, or it could be that you've uncovered a bug in 2007.
If it is possible to send the workbook to me as an attachment to an email,
I'd be willing to take a quick look at it and see if it fails on my 2007
setup or not, and if it does, try to quickly find a cause - but not with the
idea that I'm going to sit and take hours and hours of time trying to track
it down. It would have to be under 8 MB initially to make it through the
email system - my limit for email is a 10MB total size including attachments.
