Hi, I just encountered this problem. It seems that there is another thread on CC covering same topic but also without a solution:
https://forums.creativecow.net/thread/8/945437
Issue: Loading a Master Clip into the Viewer and pressing Shift+F fails to locate the Master Clip that was just loaded. FCP thinks that the master clip is not present.
Copying the clips to a new project seems to restore the Viewer to Master Clip link but does not restore the Master Clip to Affiliate Clip link.
Can anyone with this issue replicate my experience? It feels like this might mean my project is corrupt. I am new to FCP so is there a step I am missing in trouble shooting this?
Notes: Restarting FCP had no effect. Saving Project As had no effect.
Using FCP 7.0
