Hello Ken:
Create the form with the caption you want to appear in the task bar as a "top level form". You may want to "SCREEN=OFF" in your config.fpw. Create the the child forms as "in top level forms". You may want to make the child form a little smaller than the "parent". Leave the child forms Desktop property false.

.. write a program:
do form ParentForm
do form ChildForm
.. if you create more children, add them here!
.. and save it
Then do your program.
Note how the child moves inside the parent's container. Modify the child form and change the Desktop to True. Run the program again and note the difference.
