New member. Glad to find others with exactly the same problem.

Catalyst: Immediately started getting problems after upgraded firmware from 3.1.15 to 3.6.7 (going by memory on exact versions). Also upgraded Pronto Edit NG at the same time from 2.0.6 to 2.1.1. Is it possible Pronto Edit is the problem, not the firmware?? I have since downgraded to previous firmware, still have the problem.

Symptom: At first, calibration would be off by 1/4" to 1/2" every night, and need to be recalibrated. After 3 weeks, touch screen completely unresponsive. After much mucking with, managed to reset the unit only to get stuck on calibration screen.

Date first observed: Not sure, may be as early as June 5th

Firmware: v 3.6.7 and v 3.1.15 (?)

E-Mailed Pronto team: Yes, July 3rd, after reading threads here on this forum.
