Hi Michael,

Thanks for your help.

I had modified a few files and then done a 'git commit -a'. It was
only after this that I did a status and realised that I had switched
to a different branch (and forgotten). Unfortunately the branch I
switched to tracks a remote that is my stable release so I'm a bit
precious about it. If I forget again and push it, I'm in trouble :-)
Yes, I have done that before!!

Howard
