Adding onto what Kynvuu said, try adjusting the video settings to more accurately fit
your screen dimensions and rendering system. From what I've personally experienced,
Open works better on Mac, and Direct with PCs, but that's not always the case, so play
with it a little bit.
Also, could you clarify a bit about what you mean by the game "hanging" on you? Is it freezing,
is the tab disappearing, or is it put into eternal none response?
