Hi there, i get the following error message every time i open and close Microsoft Word and Excel

For Microsoft Word:
Microsoft Visual Basic
Compile Error in hidden module: Auto Exec

and for Excel:
Microsoft Visual Basic
Compile error in hidden module: AutoExecNew (when i open it)
Compile error in hidden module: DistMon (when i close it)

My friend reckons i've got a bug on the program somewhere, i was wondering what you guys would make of this. After the error box comes and I click 'OK', i can still use the programs fine. I'm working on XP Professional SP1.

Really hope someone can help remove this annoying thing, cheers!

If that doesn't apply to your problem try reinstalling office 2003 (or word & excel). That should most likely fix the problem.

I did try reinstalling Office, but no joy. That link you gave WlkingMan seemed to be talking about some really complicated stuff, i mean more complex than my sudden problem, because for a start I don't use MathType. Thanks though.
Oh can't anybody, ANYBODY help me out here?! The error is so annoying cos it loks harmless, yet could possible develop into something bigger.

The errors are usually caused by an Adobe plugin. If you go to the XLStart folder in your profile (C:\Documents and Settings\"your login"\Application Data\Microsoft\Excel\XLStart) and move the PDFMaker.xla out into the Excel folder, the errors will go away.
