Wow, I've got a new issue I've never seen before. I have two identical workstation using shared storage. One of the machines quits Final Cut every time I try to open the preferences pane. I have tried restarting the machine several times, closing the current library and trying a different library. It happens in both libraries. I've opened up the same library on the other machine and no issues. Can I clear some sort of cached memory for FCPX to see if that will help?
