John,

The change in the shell script didn't dop anything. The crappfaker keeps
terminating, and VMD runs withouth Chromium. It would be great of you could
give it a try and let me know. I'm also goingto try to upgrade from the CVS
and see how that goes.

Thanks a lot,

-Cesar

Dear Cesar,
   It could be that the vmd startup script is preventing the chromium
startup scripts from doing what they are supposed to. You might try
changing the VMD startup script to set any environment variables that
Chromium needs and see if you get any different behavior. Does the
startup code in Chromium manipulate LD_LIBRARY_PATH or other environment
variables? You might try changing the first line of the vmd startup script
so it reads:
#!/bin/csh -f

instead of the default which is usually
#!/bin/csh

See if that changes the behavior at all, you might be having an
interaction with your shell rc files...
Let me know if those make any difference.
If not, I can probably try building Chromium here next week and see
if I can get it running locally.

   John
