This is an interface problem. If you are in full screen mode and type Command-G, the screen will go black. A cursor may be visible, but the whole screen is black. The first time this happens and you do not know what is going on, is ver disconcerting. You think the system has completely been hosed. It is putting you in Property Page View, but cannot do so properly in full screen mode. That menu item should be disabled in full screen mode. Windows XP running on a Macbook Pro using RC1. Thanks. - Jim PS: Great product, can't wait for full USB, and other device driver support to work properly. 2GB orf RAM has made a BIG difference in performance, especially when switching environments.
