This is difficult to explain, but I'm completely stumped... My Roto Brush doesn't cache propagated frames. Everything else works fine, but I can't freeze the Roto Brush because only the current frame will stay green (All frames before/after do not stay green). The only option is to let Roto Brush propagate from beginning to current frame every single time, which takes forever...

According to Adobe, Roto Brush uses the image cache to store propagated frames. I've tried purging, cleaning the database, and changing the cache directory. Nothing has worked.

Here is a visual representation of what is happening:

My first guess is that you're running very low on RAM. If other applications (or even the operating system) are making demands on your RAM, then the cached frames will get dumped.
