[Xquartz-dev] IDL Users, I need help please

I know there are a few IDL users on this list, so could someone please jump in on this ticket and help figure out what's wrong with the users's system: http://xquartz.macosforge.org/trac/ticket/310 It looks like IDL just isn't starting... starting IDL triggers X11 to launch, but IDL itself never "shows up" ... so I'm guessing IDL crashed or something like that... How can I instruct the user to launch IDL via the command line? Is there a simple way, or do I need to tell the user to launch /path/to/ IDL.app/Contents/MacOS/IDL or something like that? Thanks, Jeremy
