I'm having a problem with the windowed mode game size. I'm using a Mac (Macbook running OSX version 10.6.3) & I cannot get the screen to be small enough to be able to even click play on the orginal start screen. I only have the option of clicking "windowed mode" which just minimizes it to the bottom.
I probably should send a request or something in because it looks like this topic here is a week or so old.

The game works fine on MacBooks running Snow Leopard, as long as the display resolution is set high enough. You should check your Mac's System Preferences and make sure that the display resolution is set to a resolution higher than 1024 x 768. Since MacBook displays are wide-screen, you should choose a resolution that wouldn't have to be stretched to fit on the display.
