Q: New Era - Closing the main top

Hi all, I'd like to be able to have a normal top window which functions as a stand-alone program but which also can be tied together by a main menu program. I'm attempting to do this by using a dummy program as the main top window and hiding it while the normal top window I want to run is in operation. However I'm having trouble figuring out how to close it when my normal top closes without embedding a reference to my main window in the normal top window. Any advice on how to do this or a better method to achieve the same result? -- TIA, Kelly [To reply directly remove "_" from address]
