Really weird, after encoding a mpeg2 file and quit Compressor 2, the Finder just fly away. It didn't freeze, but all icons disappeared and the menu bar is always showing/hiding whitout reason. I can open any other applications, but I can't navigate on my Mac, I can't open any Finder windows. Tried repair the disk with DiskWarrior and TechTool Pro, nothing to do. I can't even go to my Applications folder to start Disk Utility to repair permissions.
