Thanks fly. I started playing lefty about New Year because I had been struggling with a left hand tendintis from too many barre chords. About Christmas time I started to do some practice again and got the pain back immediately. Starsailor challenged me to play lefty (thanks Chris) and it was brilliant. Starting again from scratch, but no limit on how much time I could play for. Since then it has been lefty only.
Thanks for the info on the software. I'll check it out.

One good thing about music is that when it hits you, you feel no pain - Bob Marley
