I can't help. I can note some problems in your message, though.

1) No pictures. Simon LOVES pictures, especially when they show setup details.
2) Simon is busy right now with a paying customer and a deadline. So he can't
help at the moment.

Some things that might help when Simon can get to it include:
1) Picture(s) of SDRC that show its setup.
2) Serial port logs that show what is being sent to SDRC via the mousewheel,
which is placed where?
