>I have a form that uses a frmPages class. The frmPages class uses pgfBase class. If I run the form and just exit out of it, then pgfBase has all it's method code "invisible", but frmPages is just fine, and all other classes appear just fine also. It seems that all classes that were instantiated with the form would be messed up, but only the 1 is. That would seem to indicate that there is some pgf object still hanging around in memory, but not a frm object.

It's hard to say without seeing the code. Are any objects created with addobject or createobject? or are the all added via the designer at design time?
What is the baseclass of FrmPages? I assume pgfBase is your base pageframe class.

Is there a difference if you close the form with the upper right hand x versus closing it with a close button?

Is there any special code in the destroy of your objects?
