Window disappear

arggghhh!! :smiley:

i'm testing my game on the long run and something strange happen: the windows just close, i can't see it any more, but in the console i see my program running happily without any error(?), and also my BasicGameState.update() still get called(it prints update duration on the console)… It happen after some time the game is running, the model are loaded/created only at the beginning, then their position is setted by synchronized class updated by the engine thread…

Ah seems that happen randomly after i minimize the window (not when loose/acquire focus).
