So I just got my iBook G3 set up and I was working with iMovie. When I went to export the video, I tried to export to QuickTime. This is where the problem came in: When I select "To QuickTime" from the drop-down menu of targets, the window disappears. I can export fine on my Power Mac using the same OS version (9.2.2), the same iMovie version, and the same QT version (version 6). Does anyone know why this issue is occuring?
