the mouse is invisible without any cursor replacement and you're forced into fullscreen mode without any way to get out of it, is there any way to remedy this? i can't really play without some way of knowing where my mouse is...
This is a new one by me - I get my default mouse (as do at least some others, since I've gotten comments about late game play from people who have made it all the way through.) I guess I'd start troubleshooting by asking for your OS. Dumb question, but you don't have your mouse pointer set to a flat black icon, do you?
