I just purchased and installed CS5 Production Premium but now Quicktime is not running correctly. Symptom: say if I go to YouTube, the clips don't appear, just the audio, and the toolbar does not show all items. If I click on the blank picture, the clip plays in full-frame only. On other sites, clips do not even show up as full-frame, but audio is okay.
I'm running a mac clone: plenty of power and storage. OS 10.5.8. I updated my Mac software, but did not cure it.
