--text follows this line--
When I started rterm.exe (V 1.9.0 patched) in emacs on Windows XP  by M-x R and I did not use any graphics-commands,I could close R correctly with the R-command q(). If I plotted some graphics before q(), rterm.exe and emacs.exe hanged and I had to shut down rterm.exe by the windows task manager. 

I had similar experiences also with Xemacs on windows XP and with an older version of emacs and ess on windows NT and windows 2000. When I used R V1.7 or older, there were two error messages when quitting R in emacs, but I did not need to shut down rterm.exe by windows task manager.

Now I have found out how to overcome this problem, which might help you to find the problem in rterm.exe and/or in ess: if I use the R-commands
 .ans <- winDialog('ok', 'Initialization complete.'); rm(.ans)
before any plot, everything works fine!! winDialog() seems to initialize some protocolls correctly whereas plot(x,y) does apparently not!? 

Regards

René
