MS Visual Basic error on Launch
 

Sorry for sketchy info, but this is a student's laptop not available to me at
the moment;

Office 2003, up to date
WinXP up to date
Dell LT

On launch, XL loads as normal but always produces a small error msgbox
containing "Microsoft Visual Basic" in it's title bar. The content of the
message is simply the number 400 along with the red circle/white X, and
buttons labeled "Help" & "OK". The Help button launches a totally empty help
window regardless of internet connection or not. OK dismisses the msgbox & XL
seems to run fine at that point. Can even launch VB with no problem.

Issue is more of a nuisance than anything else, but would appreciate any
insights as to what is triggering the msgbox & how to correct it.

User has reinstalled Office with no change in behavior. No other Office apps
produce the msgbox.

Thanks for your thoughts |:)
