  It does work correctly in real CAVE. It also used to work with 1.7.1.

  OK, I have tried to drive the CAVE display with 1.8a21 and it sort
  of works. Now I have another problem, as VMD does not respond to
  (some of) the manipulators. I hope this is only a configuration problem.
  If You have any suggestions, please share.

  We have three manipulators, connected via the Flock of Birds sensor
  system (well actually four, two of them being a pair of pinch gloves).
  Among them, only the 3D-sensor mounted on the glasses seems to be
  functional. VMD does not respond to a workwand, neither to the gloves.
  The trackerd configuration is functional as for other programs.

  We tried to delete the glasses sensor configuration from the trackerd
  config file, in the hope that it will then see the other device, but
  without success -- it just stops react to anything.
  I also played with .vmdsensors file, changing the
  cavetracker://local/cave and cavetracker://local/cave:0,1,2,3 lines
  to cavetracker://local/dev/ttyd3 and cavebuttons://local/dev/ttyd4:0,1,2,3
  (these are the ports where the devices are connected). No luck.
  Actually, it still works the same way.

  I am able to load a molecule using the mouse and menu on the local
  console, but I am unable to do anything useful within the CAVE,
  (apart from the nice display, of course) -- cant't access the menu nor
  manipulate the molecules. I am not aware of any error messages since I
  don't see the terminal window. Possibly it is not displayed by VMD,
  but since the axes seem to be a little below the floor, maybe the
  terminal window is even lower :-).

  I will have a look on these examples.
  Thank You for help,
