Dan, I think you sent them to ME. I forgot, but I'll look again.
Fran,
I don't really think it's carpal tunnel. I think it's a little arthritis. I remember having a similar problem with the G800. The SD1 keys are not that heavy, but still heavier than I've been used to all these years.
I'm getting an Edirol M80 controller. Maybe it will help.
Thanks,
DonM
