ESS hangs when starting R from Xemacs

[Scott, Steven]

ESS hangs when I start R (by typing M-x R) in Xemacs.  I get a gray
bar (fontifying...) at the bottom of the screen.  The bar disappears
almost immediately and the message "Type C-h m for help on ESS version
5.1.21" appears in the command line.  Xemacs freezes (basic commands
like C-b and C-f do nothing).  After about a minute I get "Timeout
waiting for prompt.  Check inferior-ess-prompt or ess-loop-timeout."
Although nothing ever appears in the *R* buffer, the R process seems
to be running because when I type C-xC-c Xemacs asks if I want to kill
R before I quit.
I think the problem is with ESS rather than R because I can start
either Rgui or Rterm from the command line with no trouble.
_____ My system: _______
1) Windows XP running Cygwin
2) Xemacs version 21.4 running cygwin as a shell (i.e. when I type M-x
   shell I get a cygwin BASH shell)
3) R version 1.7.0
4) ESS version 5.1.21
