I have a ComboBox control within a form that has a lot of code in the InteractiveChange event. After user has made\changed a selection and the code has fired, the value the user has chosen has been 'wiped out' of the control.

After spending a lot of time re-writing my method code without success, I entered NODEFA as first line of InteractiveChange - and never called DODEFAULT() within InteractiveChange event. The control worked fine this way (i.e., value was displayed in control).

Is there any way to access the VFP ControlBox base class so I can step-through the code to find the "glitch" (or 'feature') so I can possibly change it?

Thanks - Victor
