Error when opening Excel - compile error in hidden module

[sundevils]

Each time I open or close Excel I receive the following error
Microsoft Visual Basic
Compile error in hidden module: DistMon

Look into Visual Basic Editor | Tools | References.

Probably something will be marked as missing in this list. If so, you should find missing file.

Same problem. Excel 2007.

The only module loaded is "AcrobatPDFMaker (PDFMaker.xla)" and it's password protected. I can't check the status of this file but suspect its missing since a search doesn't fine it. I removed, using add/remove, PDFMaker using the Acrobat 8.0 Pro "repair/modify" option. I have no files in "c:\documents and settings\owner\application data\microsoft\excel" and "...\excel\xlsstart".

So, any ideas? It's not a show stoper but is just a pain since it happens every time I load or close Excel.

Thanks.
