When my ZC Is in full-screen mode it works but half the screen and occasionally the entire screen flickers black like an old tube TV that's about to go out. I was wondering if it was fixable or if I could get a mid-size screen (I don't know how to change out of full-screen)
Diplay Issues
Hitting esc brings up the menu while playing. You can change fullscreen there. For the flickering; Pre 2.5 versions don't really have any rendering options if something like that happens. ...Unless it's a vsync issue, then you can change your gfx cards refresh rate to 60, or turn vsync in zc on.
