Never used MatchEntry myself. You can solve the first part of the problem by setting ComboBox.Style = fmStyleDropDownList (Properties Window).

As for the rest of it, I have no help. I set up a test ComboBox. With .MatchEntry = fmMatchEntryComplete, the best I can do is get it to match the first letter, but even that stops working after hitting enough keys.

I have a feeling that you might be out of luck with this one.
