R help - May 2006 - "Process R is not running" on emacs 21.2.1 using ESS 5.3.0 and R2.3.0 on Mac OSX 10.4.6

Dear R-helpeRs,

I was not sure if this is ESS-specific or Mac-specific etc, so I send  
in the main list. I had the setup emacs+ess+R 2.2.1 running fine (on  
a powerbook G4).

I recently upgraded R to 2.3.0 and it runs fine from the GUI and from  
the terminal. However, when I try to run it from emacs (which was  
running fine with R2.2.1) I get the "Process R is not running"
message.

I upgraded ess to the latest version 5.3.0 (in case it had sth to do  
with it), but it did not help. I also ran emacs as root (an old  
message in the list suggested that this helped, albeit in a different  
setup), but the result was the same.

Any suggestions?

TIA

Costas
