I've downloaded the free trial of FCPX. I have a late-2008 iMac running Lion with 4GB of RAM and a 3.06 GHz Core 2 Duo (so I'm pretty sure I meet the requrements, no?). For some bizarre reason, the app always hangs on "restoring the window layout". Clicking on the app's icon when this happens brings this up: https://discussions.apple.com/servlet/JiveServlet/showImage/2-16227805-38301/FCPX.jpg Going into fullscreen half-solves the problem. I can interact with the UI (even import footage!) but the loading screen is STILL there and the UI is definitely glitchy: https://discussions.apple.com/servlet/JiveServlet/showImage/2-16227805-38302/FCPX2.jpg I've tried going through the "basic troubleshooting" steps they have, but none of the preference or recepit files mentioned in the document even exist. I updated everything there was to be updated. I've even deleted, re-downloaded, and re-installed it. What the heck is going on?
