At the moment FPL have no way to let you handle the os events directly. It just queues it up internally so you can fetch it later, but this is wrong and needs to be fixed. So i am fixing that right now.
But this will result in a api change regarding fplWindowUpdate(), fpl*Event() and so on.
Also the impact of change will be very huge, because it affects all window and input handling.
I dont expect that to be done very soon so maybe it will be done by mid of october, but i cant promise :-(
