Preventing fullscreen flash Projector from minimize/close (trapa all keys)

programming flash
1

hello all

i´m producing a flash projector to run on a windows pc, and it will be displayed on an event for people to play. Will be a fullscreen game.

Is there a way to prevent people from typing ALT+F4 and closing the projector?

I´m already using fscommand trapallkeys, but it does not work for ALT+TAB and ALT+F4.
Is there a way from blocking all that?

thanks
