Bryan:

Comboboxes are so troublesome in VFP (3.0 & 5.0) that I avoid them where i can and use a simulate cb by combining a textbox/listbox or textbox/grid.

I have never seen this particular problem, though. Seems like the handler's logic must be bypassing your interactivechange() handler somehow.

Is the problem in the ic() handler of the problem control or in a parent class?

Have you traced to see if the ic() is being triggered?

I know that I have more problems with combdropboxes that with combolistboxes. The IC() handler of a combobox set up a a drop box seems to have may problems. These are usually solved by styling it as a combolist.

If you put a lot of code in an combobox ic() or programmaticchange(), the displayvalue will often not update. If you put a call to an object outside of the hierarchy of the combobox (as to another form or oApp) in GotFocus(), the list will not drop. Could be related.
