[phenixbb] phenix gui freezes

This is good to know; I'm glad it wasn't symptomatic of a problem with  
the code for the GUI itself.  It would be good to know if the outgoing  
connection is causing problems, or just the incoming connection - the  
latter is much less important.   For now I will add a preference  
setting to disable the "server", and if that still doesn't solve the  
problem I'll disable both directions.  (I may drop by your lab and ask  
to test it next time I'm in Cambridge, because I'd really like to know  
what part of Linux is causing socket problems.  Are you running a very  
restrictive host-based firewall by any chance?)
