Update: The screen clipping is only in windowed mode. I couldn't see the options button, but pressing escape and selecting full-screen solved the problem :)
Haven't played in a couple of weeks, back now. Problem I have though is that the edges of the screen are gone: I can't see the options button or the 'close' button when I access the market or garage etc. Bug aside, damn fine game! All the best!
For the speed toggle: Hold space, click outside the game window (but don't click on a link) then release. Game stays on fast, and you can still click on stuff with the mouse.
