A friend has Excel 2007. When he opens the program (not a file, just the
program) he gets the following error message:
Title: "Microsoft Visual Basic"
Msg: "Compile error in hidden module: DistMon"
When he clicks OK in the error box, the box goes away and all appears to be
working.
Question: Why does this error appear and what is the significance of it?
Thanks for your time. Otto
PS: I have 2007 also and I don't get this error.
