I have an IMAC, MAC OS 10.7.3, 2.66 ghz, 12 gig memory computer. Lightroom 4.0 works fine with all my images but when I go to import movies from one large folder, lightroom freezes my mac and I have to do a hard reboot. Right now I am afraid to import movies into lightroom because of this issue. I tried reinstalling Lightroom but that doesnt fix the problem.
