I know how to define a Form as Top-Level Form. The question was: Have I to expect any problems if I use the FoxPro screen as top-level screen and my forms as In Screen-Forms?

>>I've heard on German DevCon that I have to create a COM-Exe to implement a Server that can show forms. Also I've heard, that this form must be defined as "As Top-Level-Form", to become visible. I implemented a COM-Server-class, that has the statement _SCREEN.VISIBLE = .T. in its Init-Event. This makes popup the FoxPro Screen. In this screen I can put forms in the way I usually do in FoxPro, the forms are defined as "In Screen". Did I do anything wrong, that will result any problems in the future, or can I go forward this way?
