>So I have figured out the combobox's main characteristics. But now I am trying to get the IncrementalSearch property (it's set to .T.) to do what its name implies. When I pop up the combobox list, typing anything immediately closes the list and I see the character I typed in the collapsed combobox (what is the correct terminology for the collapsed combobox object?).

Try to set combo.style=2 (dropdown list). That limits the values to only those listed, and incremental search should work.
