You need to put your application into a wait state. In your main program, add a READ EVENTS to do this. Ex.

* some setup code
do mymain.mpr
read events

* do some clean up code here

From your main menu, you can launch any of your forms. You can also set up a menu option to issue a CLEAR EVENTS to exit the wait state and proceed to the next line after the READ EVENTS.

HTH.
