help me, even though the game display set as my windows resolution, it still have the menubar and taskbar, anyone can tell me how? by the way, it doesnt hurt the game play but it hurt my eyes....

try press alt+tab while playing. this may switch the game to full screen.

actually the alt+tab function does not activate full screen
it just opens another screen and brings it up

are you sure your com has the proper specs?
and besides X8 are you sure that you put X8 at full screen and not just your screen resolution?
