David,

It sounds like you have an outstanding object reference to an object internal to the form. You have to make sure you you release all object references. You can use the objref tool available on my website it's under Q&A, OOP

>No, I am not issuing a CLEAR EVENTS because I do not want process to stop when a user hits the exit button on one form. The funny thing is that this is a base class that I have been using for a couple of years and never had problems with it before.
>
>When I query the object references in the form manager they are .F. or NULL, but the form remains on the screen anyways.
>
>Once I do issue a CLEAR EVENTS from the "Quit" menu option and the subsequent RELEASE ALL and CLEAR ALL are issued, the form disappears.

>I'm not sure where to go to from here besides a complete redesign.
