Tim,
You are going to have to pick a different trigger point for changing the RowSource. You have to call the Requery() which lets it fully adjust itself to the change and then it should paint properly when dropped.
>On VFP8 I have code which changes the row source in a combobox when the DropDown method is executing. When this happens sometimes I get a shortened drop down list with little scrollbar like arrows that don't function correctly.

>I have not pinpointed exactly when they come but I think it has to do with the number of records and the rowsource changing when the dropdown is executed...

>Then the second time I execute the dropdown the list appears normal...
