Usually it's considered good form to keep the mailing list in the CC.

I am afraid I can't help you of the top of my head. Here are some generic
tips:

   - Are you using the latest VMD version?
   - Is the problem repeatable if you restart your computer
   - Is the problem specific just for your current 3D structure or for any
   3D structure? (so have you tried with another pdb/psf pair?)

HTH,
