Besides constant crashes, I've been encountering a strange problem with Premiere CS3 lately. For some reason, after I've been working on the project for several minutes, I start to get time line distortion. For example, moving clips around can cause small artifacts of that clip to remain in place, the scrubbing bar (the red vertical line indicating time position) will also leave ghosted artifacts everywhere when I scrub through the footage and finally, clips will snap to others, but will show as separated (even though they are in fact seamless when I play the preview).
Also, the OSX dock menu can sometimes get imprinted on the application window and will only disappear when I minimize the program.
Any idea what could be causing this? I'm figuring whatever the problem is might be causing my crashes too.
