Hello folks, I just called Apple about the following problem. When I am in a video chat with a friend and using iChat theatre for sharing a PDF/Image, iChat does not switch into the 3D perspective but simply exchanges my picture at my friends iChat windows for the pdf/image I am sharing. He is unable to see my video anymore and vice versa. Apple was unable to solve the problem. Techspecs: - Both systems on OS X 10.5.2 - Chax installed (3D used to work while Chax was installed) - Internet: Both approx. 2000kbps down, 224kbps up When using the connection doctor, all capabilities fields except 'host multi-person video' are checked. Anybody knows how to solve this? Thank you in advance.
