I have a modeless form with buttons that launch other forms (also modeless). Each child form has a custom property that links it to the parent form. When the parent is closed (by clicking the X) the Destroy code loops backwards through the forms collection array and checks each form for the property linking it to the parent. If found it executes _screen.forms[lnCount].Release().

In development mode, everything works just fine. However, when running the .EXE, if more than one child form is launched, when I attempt to close the parent, the X greys out and nothing is released.
I've determined that QueryUnload is being called but not the parent form's Destroy(). I've checked for object references that may not have been cleared but have found none. I'm at a loss to explain this. Any ideas?

TIA
