I'm trying to screen share my Imac with my G4, running OS X 10.5.2 on both machines. From the G4 to the Imac the screen sharing works fine. Screen sharing from the Imac to the G4 worked once this morning. Now when I activate screen sharing from the Imac to the G4, the screen pops up but you can't view anything. I can control the G4 from my Imac, I just can't see what I'm doing. The screen is white with purple lines every where. Hope someone can help. Thanks
