On mac with firefox, game does not begin to play. All the bubbles stick to the top left corner until you resize the screen, after which they perform their duty, floating up and running from the mouse. The chat window shows but no usernames next to messages.
With safari, chat names show, bubbles do not stick and game begins to play. However text does not appear and certain graphics in the painter bar to not load, neither can they be clicked.
Mac 10.6.6, latest Firefox/Safari
