OFF: "Compile Error in Hidden Module" Error Message When You Start
Word or Excel

It points at PDFMaker.xla as being the culprit.

Hi,

I'm using Office 2003 Pro. All of a sudden, when I open my excel I get the
following msg:

Compile error in hidden module: AutoExecNew

I can click OK and continue working. When I close Excel I get another msg:

Compile error in hidden module: DistMon

Again, I can click OK and save my work and continue working.

I tried an Office repair and reinstall but that didn't take care of it.

Thanks,

Mary
