I had recalibrated the touch screen just about a week ago or so. These problems occurr with the hard buttons as well as the touch screen. The setting on the RFX-150 was set mid way, 12 O'clock. I have turned it to minimum, 7 O'clock. I'll watch it and see what happens. Since no one else has picked up on this thread, perhaps we should communicate off the forum.
Experience is what you get when you don't get what you want. Any wire cut to length will be too short. I must be a near GENIUS. All my teachers told me I was at the very PEAK of the bell curve!
