I have a couple of problems with pymol 0.98, but they only happen once in a while and for no apparent reason.  The problem I'm having right now is that pymol just won't start up.  I double-click the pymol icon (or try to open a PDB or pse file), it goes into the 'launching pymol' routine, the pymol tab appears in the bar at the bottom of the screen, but then a second later it disappears and pymol never starts up.  This problem tends to go away on its own, but sometimes it takes a while.
The second problem is that occaisionally the pymol graphics will become very slow and choppy.  It seems that somehow the graphics card isn't getting used anymore.  This problem can always be fixed by restarting the computer, but it's a bit of a hassle.  I guess this might be an OS problem rather than a pymol problem.

My system is a pentium 4 running Windows XP with an NVIDIA Vanta graphics card and I'm running the precompiled binaries of pymol.  I know this isn't much information to work with, and I can certainly live with these issues, but if anyone can think what might be causing these problems I'd like to give a shot at fixing them.
