I have had similar problems on a macintosh G5 (dual 2.5 GHz, Nvidia GeForce 6800 Ultra DDL graphics card). It sometimes suffers from a progressive slowdown of command execution over 5-10 minutes of use and eventually becomes unusable. Save session, quit, restart program, restore session fixes the problem temporarily.

If there is progressive slowdown, then there might be a memory leak that we are unaware of. Please use chimera's Report a Bug dialog (in the Help menu) and replace the blue text "(Describe the actions that caused this problem to occur here)" with a description of what kind of data you're looking at and which tools and commands you use to manipulate the data. And please include your email address so we can ask for more information when we can't reproduce the bug (and let you know when it is fixed). Ideally, you'd attach a command script that replicates the bug, but some information is better than none. Greg Couch UCSF Computer Graphics Lab
