I'm having the same problem on a G4 Cube running MacOS 9.04 with all the latest software updates available from Apple. The Cube has a single G4 processor (450 MHz) and an ATI Rage 128 Pro Video Card, Model ATY,Rage128Pro, ROM 113-72701-125, Rev 0. I see white text on a black background ("CD-ROM Required" and then "OK" inside a blue box) in the dialog box that pops up if I forget to insert my CD before starting the application. All other text dialog boxes are blank and black. For example, using command-q, I get two black dialog boxes. Clicking on the left box quits the game. I have no idea what the right box does. Another example, in the status window in the lower left of the screen, I can see text such as "Ammo", but the box next to that is blank and black.
