10.04-4 LTS, with a frozen kernel because its built to run with rtai, 
controlling metalworking machinery.

Something else I might toss into the clue pile, it never works if either 
end of the thing is gedit.  A copy from vim's screen will generally work, 
but vims copy seems to be a direct screen scrape, so the resultant paste 
needs heavy duty corrections since the white space will be AFU in the 
paste.

I'll keep track of what I'm doing a little better & see if at some point I 
can make 2+2=4.

Thanks Colin.

Cheers, Gene
