X11 problem with R 2.7 OS X 10.4.11

I must have missed these emails being sent around, probably because I 
only just now updated to 2.7.  I noticed here that:

https://stat.ethz.ch/pipermail/r-sig-mac/2008-May/004981.html

Joerg is saying that he's having problems running R plots from the 
command line when the plots are going to X11.  I have the exact same 
problems he is discussing, although issuing the `x11(type="Xlib")' in 
one session does not help me in future sessions.

The main purpose of this email is to assure Joerg and others that he is 
not the only one experiencing this.

I feel that this is a major issue, because I'm a big emacs fan, and 
running R through ESS is essentially running it in the terminal.  So I 
can't run graphs from emacs without this ugly workaround.  Any help over 
the matter would be greatly appreciated.

As a side note, and one I was experiencing with previous versions of R. 
  If you issue the command 'dev.off()' in X11, R instead opens about 3 
other graphic windows.

Thanks in advance for any input on the matter.
