Cheryl,
The ObjRef tool from my website should help you track down the dangling ref. It's under Q&A, then OOP. It seems to work better getting from my webpage instead of the Files section here.
>When I click the close button on my bizobj form of some kind, most of the close processing happens, the form's obizobj is set ot null, but the form does not close. The next click yields an error in the form activate because obizojb is not an object. Just opening the form and closing it works OK.

>I added a combobox to a reportform subclass and sometimes get the error there, too.

>Anyone come across this and figured it out?
