I just had some troubles - I changed the index of a combo during startup (applying the settings), but the combo showed a wrong value.
Then I figured out, that the reason is that the combo had its .Text property <> '' and this value was applied when setting the localisation (from .PO).
I set .Text to '' and now the combo shows what it should.
Shall I take care that Combos shall always have empty .Text properties or shall I do sth. else?
If it is the first case, maybe I shall take care of emptying some properties of other controls, too? Which are they?
