I just tried it on my laptop which has the "old style" x11 installed,  
the one whose icons on the Dock is the plain white one with a grey X,  
and which labels itself XQuartz 2.1.6 (xorg-server 1.4.2-apple33).   
I'm unable to get it to "hang" except for the fact that when the  
window opens, the focus is shifted to that window and typing causes no  
response until one clicks back into the (GUI) console. Repeated  
invocations of x11() without plotting do not cause R to "hang". So I  
guess my only contribution is that an older version of OSX and X11  
does not necessary cause this problem. And I would request a better  
decription of "hang" on Mr Love's part.
