  In VB6, the App.NonModalAllowed property would tell you whether you could show a modeless form or not. The docs for .NET say... "No equivalent.

The .NET common language runtime automatically manages this behavior." ...which does not explain what is happening.  I'm guessing that the clr shows the form as modal if non-modal is not supported. I have a .NET class library which ...Show All
