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.
