Vista - HOney, I shrunk the command buttons (in Excel VBA)

Hello,
I have an Excel VBA App which never had this problem before but when testing
underVPC 2004 I through automation had saved a workbook's contents in another
folder then again thru automation reopened and pulled those worksheets back
into the original workbook. It had always worked before but when testing in
VPC, 8 of the 9 command buttons on the sheet where the code work was done
reappeared shrunk very small, and when I clicked on them they shrank all the
more. The only command button that was not shrunk was the one for the code
that did the saving.
Any ideas if this could be a fluke &/or VPC issue?. Didn't see any such in
list of VPC issues.Thanks
