This morning, R (2.2.1) was working fine.  I quit the R GUI, opened  
it later on, but R failed to completely load.  The program opened up  
fine, the working directory changed to the appropriate one, and then  
the GUI quits.  The typical welcome (with version info, etc)  does  
not come up.  There was no crash error in the Finder, and I can't  
seem to find one in R's crash log.  I am able to call R from the  
terminal.  I tried downloading the nightly build but this doesn't  
seem to work either.  I have also tried installing previous versions  
of R (2.0, 2.1, 2.2.0) and the same problem ensues (note, I can call  
R from the terminal with the earlier versions, too).  I am running  
the system below.  Any thoughts?

Thanks,
Alan
