Eli,

Thanks for your help.

I did restart Emacs, indeed I re-booted the PC. I modified the PATH via My
Computer|advanced|Environmental variable, and I have re-installed Grep.

In the end I gave up and installed Emacsw32, which comes with Grep, and its
now working.

I would rather have solved the problem but, for now this seems the more
efficient way of sorting it out.

Should I have added anything in the .emacs file?

Graham
