I wanted to follow up on this. I tried my SET button again this weekend, and it does work. Not sure why I thought it didnt. It would be incredible if we could get RES/CANCEL working too.
Interesting. So every single button on the left works, including the LIM button?
I have the same button set, and not all of mine work. Enough, mind you, to use and keep them, but this tells me there some coding that could possibly be done to get them all working.
