MDI applications

Question:
I am trying to build a form that can be loaded as either MDI or SDI. If a use the SetParent API to force the window to be a MDI window it works.....but when you click the mouse on the caption bar or border the window suddenly moves away from the mouse. Is this a bug in NT or am I doing something wrong?

Answer:
I wasn't aware of the way you are using SetParent would work. Unfortunately, I do know that you can't change whehter a form is or isn't an MDI child on the fly. You have to specify it at design time and cannot change it at runtime. This is probably the limitation you're running into -- you're just getting to it a different way.
