.Last( ) taking keyboard input hangs on command-Q

Dear Colleagues,

The recent change to R.app disabling q() and requiring command-Q or the equivalent
is well motivated.  However, it introduces a new problem for a user (like me) who
has a .Last() calling for user input, e.g. dialogs on choosing final actions to be taken.
Please use R 2.11.1 as this has been changed for some time and report if the issue still exists (with a reproducible example).

Thanks,
Simon
After command-Q,
the console cannot accept keyboard input, and clicking on any of the buttons 
Don't Save, Save
does nothing.
Clicking Cancel works, but once you've clicked Don't Save or Save
clicking Cancel no longer does anything.
Then R.app has to be killed the ungracious way.

Thoughts?  Thanks.

Thanks, Simon, for your reply.

This is reproducible with 2.11.1, both 32 and 64 bit.
With the following .Last, command-Q hangs, there's no exit except an external kill,
and .RData will not be saved.

Not a big problem if you're aware of the behavior;
otherwise, one might lose a few hours of work.
I don't expect a fix; this note is meant to prevent others
making the same mistake I made one day.

On the sunny side, if .Last writes something to a file,
it completes with no problem.

.Last
function() {
	answer = readline("How do you feel now?")
	return(answer)
