Hi, folks -

We seem to be having an issue with Mac users when running a server-side
VMD window. This version of VMD is a 'common' installation for all
users on a cluster. With Windows or all tested Linux terminals, things
work fine when running it through tunneled x connections. However, the
recent version of XQuartz on OS X does not work.

Upon startup, VMD gives the error copied below (the errors shown here
are for a user-installed version, but the common version behaves the
same way). A locally installed version on the same Mac machine works
fine, and the server version, when run in text-only mode, also works
fine. It seems as though the x-tunneled graphics are not playing nicely
with XQuartz.

Any suggestions?

Thanks -
Ryan
