Hello, well open this link in mozilla or any and also compare it with chrome http://files.cryoffalcon.com/games/Animal/BMRex.html when the game loads then you press f11 while using mozilla then the game also streches to fill the screen. but if you use chrome then this is not the case, if you press f11 when the game is loaded then it doesn't strech. Only chrome doing this. I don't know where did i went wrong. thank you in advance.
