I find that the ESC key for aborting a line of code or stopping
execution and also the STOP button are not working in R 2.14.1.
I thought that this might be a Lion related issue as I updated
both my OS and R version at the same time but I see the problem
on an older machine running Snow Leopard, too.  I can't give
an example.  Just write a line of code and hit escape before
you hit return.  This used to abort the command.  Was this a
bug earlier that is fixed, or is it a feature that can be
restored?  Thanks, in advance.

Here is the session info.

R version 2.14.1 Patched (2012-01-08 r58078)

Happens on 32-bit R, also.
