Thanks, Leith.

Although it seems that that would work, I don't think I have that
option available. I am using Excel Automation from within VB, using
late binding. Unless I'm doing something wrong, apparently, I don't
get any Excel events using late binding.

Besides that, why is it that my code works in the Workbook_Open event,
yet if I place it in VB immediately after opening the document, it
doesn't?

Thanks.
