[R-SIG-Mac] ESC key and STOP button not working in R 2.14.1

The most recent email on this appears to be https://stat.ethz.ch/pipermail/r-sig-mac/2012-January/008967.html

which says, "the most recent GUI is back to the old behavior."

Does this refer to some more recent GUI than the following?

> sessionInfo()
R version 2.14.1 (2011-12-22)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

By "the old behavior" does Simon Urbanek mean mean what R used to to from time immemorial, i.e., that hitting ESC would get me out of the current command line, whether I have hit ENTER or not?

To reproduce the problem:

Start at R prompt on a Mac

type: rnorm(100000000000000000) and do not hit enter.

Hit ESC.

I do not get the R prompt. I do not get out of the current command.

Click with the mouse on the STOP button.

I do not get the R prompt. I do not get out of the current command.

How can I get R to behave as it used to behave, with respect to ESC and the STOP key?
