With netscape running on a remote machine, and its display exported to my
local redhat 6.2 machine.  If I type /usr/bin/netscape, I get another
instance of the remote netscape and not the local netscape as one would
expect.

to reproduce:
(i)start netscape on a remote computer and export the display to local
redhat 6.2 computer.
(ii)at a terminal type /usr/bin/netscape
(iii)Note that an instance of the remote netscape was started and not a
local instance, as started with /usr/lib/netscape/netscape-communicator
