Burr, thanks.

I think the problem I had was using the buttons on the logitech. They didn't seem in a good position and caused quite a bit of strain. I have the tablet set so that I hold the rocker buttons and press for double click/right click. All very easy, like using a pencil.

I really don't do any mouse work at all now, with a tablet both at work and at home. The main thing I have to do is to avoid bending the wrist back in any way and to keep the shoulder relaxed, down and pulled into the body. However, I am always open to options so any more info is appreciated.

Cheers.
