Hi, I have updated to OS X Yosemite, I am using AE 13.1.1.3, and now I am having an issue with RAM-Preview that makes working with AE problematic: When I start the Preview by hitting "0" on the Numpad the Ram Preview starts, but I am not able to stop it anymore until it has rendered to the end of the work area.
It is also strange that I am able to move keyframes while it renders.
The Shift-Ram Preview is also affected by this bug.
