About the problem with

"2: Sometimes buttons stick and send same code repeatedly (normally volume up in my case!) causing my amp to wind up to maximum volume, sending me diving across the room to turn it down manually"

I read a thread in the RTI theatertouch forum about their RTI T3. They have the same problem like you and me :-)

I think the solution is to put in delays of 0.1 seconds (or even a bit more) to solve this problem. You may noticed that iPronto Edit already build in delays when you install something new.

For me it seems that these delays are necessary somehow?!

But it's interesting that other remotes have the same problem .......

Best regards,
