Thank you, thank you, thanks you. PM was driving me crazy, with how slow it was running but resetting the preference worked and now it's running great.
Ok I jumped the gun, as soon as I shut PM down and re-opened it the lagging started again. I have reset the preferences but still it lags , this is driving me crazy. I shoot a lot of events and Pro MMA so I have thousands of photos to go through and cull but so far PM has not helped at all, can anyone help???
I'm running a Mac Pro 2008 with 12 gigs ram OS X 10.9.3
