Wel, my form is not shown here either as active or available.
I added the unit via Project Inspector using the Add button...

In the source I had to:
- Add the form unit to the uses clause and remove Unit1
- Change the Application.CreateForm call to use the specific form
- Erase Form1 from the lpr file
- Remove Unit1 in Project Inspector.

OK, so now I have to solve the dependencies that popped up regarding used units
in the now main form...
