Well the "do you want A or B" can't be ever answered with a "OK" or "cancel". Even I would answer it as "yes" (and Marc Grajower with a "no"), so you're missing a "none of the above" :).

Have you forgotten alert.prg? Why do you have to adjust your question to messagebox's limited set of buttons? Can't you make it a more natural question and provide any number of reasonable answers?

"You have entered some data. If you close now, they will be lost. How do you want to proceed" - "save first";"just close";"let me finish that first" (the last being for the case when the user clicked close button accidentally), or any such set of text and buttons.
