I just installed Snow Leopard on my Quad core Intel Mac and I can no longer customize FCP's keyboard through the save and load functions. I can drag functions to the custom keyboard window as if they work, but once I save it and load it, the keys don't do the function. It does save the buttons that I dragged to the timeline.
The only other new thing is the Mac Magic Trackpad that I am using. Any suggestions?
Answered my own question! I found the prefs file and trashed all my attempts at a custom keyboard, (they were all there), and started again. Closed and reopened FCP and now it works. Hope this helps someone else.
