I've been having a strange problem whenever I try to use my MacBook Pro's HD on the new Final Cut Pro X. In the first screen shot, you see what I see when I open the app. Note the Macintosh HD under the Event Library and its projects under the Projects Library. In the second screen shot, taken just a second later, it's gone. The funny thing is, everything works fine when I hook up my external hard drive, but it's not very powerful, and I didn't intend to use it in that manner. I wanted to know if there is something I could do to fix the problem, be it clearing registry files or something of that nature. Any suggestions or advice would be greatly appreciated. Thank you.
