I've just run up a little test in Delphi4, an Edit and a Combo
When 'D' is typed I set the Como's DroppedDown to True
It certainly captures the Mouse, but does not hide it.

However if the Cursor is an I Beam when the Combo is dropped (ie: it
was over the Edit control or the Edit part of the Combo) then the
Cursor gets 'stuck' as an I Beam

AFAIK a Combo's dropdown list is really a Parentless Listbox Window
created as WS_POPUP

It might be simpler for Stark to create his own alternative to the
Combo using a Listbox
