My Premiere Pro CS3 (part of Master Collection) on MacOSX 10.5.8 (Leopard) keeps crashing. The crashes are inconsistent and non-reproducible. While troubleshooting I noticed in the Activity Monitor that a child process of the Premiere Pro process, named PhotoshopServer, is marked non-responsive. Usually that follows by Premiere Pro crash. How can that be avoided? What is this process and why does it hang? Any ideas? Appreciate all kinds of input.
