Fixed - but didn't help.

That seems to be working - I've been running emacs-X11-24.2.90-1 for
more than 24 hours now without a glitch.

Yes, cleardiff doesn't really work in cygwin so I'm using a wrapper
script that among other things converts the paths.

I'm hoping that 24.2.90 is the way to go. Is there any point in
debugging the old version if the new one doesn't have the same problem?

Thanks for your excellent help!

Cheers!
