C-M-anything gives no response

[Robin Wilson]

Hi

I've been trying to use keybindings such as C-M-k, and have found that 
none of them have worked. I've done some more investigation and, by 
using C-h k, found that anything with C-M then any key is not being 
recognised by emacs as anything at all!

I've searched Google Groups and the internet in general, and everywhere 
else I can think of but can't find a way to solve this. I'm using emacs 
through cygwin on Windows if that helps, and it works in the native 
windows port of emacs, but not in the cygwin version.

Any ideas anyone?

Cheers,

Robin
