Let's start here...I recommend setting a breakpoint at the place where you are launching the form, and step through the Init of the form. In the Framework's CBaseForm.Init() method, you'll see code that is checking the form's "lAllowMultipleInstances" flag...is this flag set to True? Is there already an active instance of this form?
