I can host, but unfortunately B&W freezes up right after I hit the Start Game arrow in the chat lobby (B&W's chat lobby, not Gameranger). Everything works perfectly until I try to start the game. It gets stuck on the "Sending/Receiving Game Data" screen and the mouse curser no longer moves. I can CMD-Tab out to the Finder and back to Gameranger, so the machine itself is not frozen. On the other hand, when someone else hosts the game, B&W zips right on past that screen and into the game. Any ideas?
