>I've had an interesting thing in Hungary: we've had an "OK" button, and had to replace it with "O.K.", because "ok" means "a reason", and someone asked "a reason for what?".

That's interesting! I thought OK (capitalized) was fairly universal, but that's probably just my anglocentricity talking.

I think in that situation, I'd just use whatever Windows uses for its dialog boxes.

(This is one great feature of this place--the international perspective.)
