    Locking existing frames - Slows down RAM preview - After Effects CC


      How do you fix 'locking existing frames' when RAM previewing? It locks up and is very slow before rendering and I have 32gb of RAM on a 3.4 i7 iMac. I have multi-processor rendering off. It was apparently fixed in an update in CS4, but im still experiencing it. Any suggestions?
