Well, it works, but there's 2 mouse pointers - the one in the game and the one on the desktop (I'll call it the OS pointer). They don't move at the same rate so when I move one towards the middle, the other one is moving twice as much so it ends off the balrum screen and clicking changes to the window under the OS pointer.

I tried hacking the options json file (because I can't click on the options) to default it to fullscreen but that didn't help. Any ideas?

Thanks in advance
