one more thought... if you have plenty of memory on your mac, it may be that you aren't giving the game enough memory. Try locating the game icon on your hard drive, click/ highlight it and hit "apple i". Or use the pull-down menu under "file" and click on "get information". From there you can use the pull down menu and find "memory" in the box that shows up for get info. If it shows a recommended kb or mb, make the number a little bigger by re-typing it. That may or may not help. *warning* do not go crazy if you increase the memory...the game can also be a memory hog.
