3 ways to solve this nightmare:
1. declare the name of the form as public variable ( make it a point that the external name and the property name are identical.)

2. make use of the name option when activating the form.

   Do Form MyFormName Name MyFormName
   MyFormName.Activate()

3. make use of the _screen.form collection property to access active object within your app.

In addition, the windowtype property has nothing to do with this problem.
