Using VB 6.0 with SP 3 installed.

When closing my app by pressing on the "X" button on the top right part of the form, I get the message: "This application has performed an illegal operation and will be shut down" (yeah and that's what I want anyway :) )

I don't have this error if I select File|Quit from my menu, which is simply issuing a End command for now.

Anybody has a clue as what to look for?

TIA
