About 2 weeks ago, this touch screen problem started happening after working fine for the 4 months or so that I've had the remote. I don't remember the firmware, but I upgraded it when I got it, so it was the latest available in March. once I started having the problem, I upgraded to the latest from June. all that did was get me to the calibration screen. I wasn't able to get past that until today after leaving the remote sit for about a week. idunno! seems to be working fine now.
