Hello: I am having a very strange problem with my G4 (733 Digtal). It is displaying only black and white images, pictures look as though they are film negatives. This only occurs when I boot from a certain drive. When using another drive everything appears fine. I have 10.2.8 installed on both bootable drives. I have tried to run disk utility but it seems to think that the drive is in use when I try to check it, even though I have booted from the other and started no programs. It started all of a sudden, not after any changes were made. Does anyone know what is going on? Thanks, Kevin
