[Chimera-users] Running out of memory when recording movies

Sounds like a Chimera memory leak. I have made movies that use 100,000 atoms with 10,000 frames and not run out of memory. But I always make my movies using a script, not the Animation tool. The Animation tool is a prototype, it has many limitations and bugs, and it would not surprise me if it is eating up all the memory.
