Subject: 23.2; emacs gets stuck in the erase mode
Date: Sun, 04 Jul 2010 11:29:38 -0700

Hi,

I'm starting emacs from tcsh running cygwin-X on Windows 7.

Typing ctrl-k (or ctrl-backspace) results in everything in the active
emacs buffer being deleted word by word. I can only stop that by
rightclicking on the cygwin-x icon in the task bar.

See the long sequence of C-k below? I have only pressed it once.

This behavior is reproducable and so far I have only encountered it with 
the two delete-combinations above and only
in emacs.

Thanx

ML

This is very weird. Does it still happen?
I would have guessed a stuck keyboard, but you said it only happened
with Emacs.

Hi, yes, still same story.
It's kind of a dangerous bug. Once it not only caused the entire 
contents of a file to be removed word-by-word, but it didn't let me 
undo, and there were no ~-copy.
I'd say it's not a keyboard issue, since this problem never happens in 
other apps/editors.
This happens some 50% of the time I use ctrl-backspace.

I can't think what can cause this. Does it happen if you start emacs
with `emacs -Q'?

If nobody here has any ideas, you might try asking on a Cygwin list.
I see a few references to "stuck" keys there, but not the same thing as
you see. Eg
