Markus,
Good thinking - I didn't try in another form at all. I'll do that. It IS a BizObj class that's opening the data here.

Thanks,
Barbara

When a combobox class was instantiated on it, one of the class properties (an array) wasn't in the object instance. I still have that form and I can reproduce the behaviour. In every other form the class is doing as it should. I checked that form in about every way that came to my mind since, but I couldn't find anything special in it.
