Well, I re-flashed the v. 1.5.5 firmware, replaced the pcf, reloaded and still had no joy. Re-flashed again hoping to add an older version of my pcf back on, and now I can't get past the 3rd calibration corner. I have seen plenty of people with this problem, but no answers in any of the threads I've read. This is the serious version where using a stylus and being EXTREMELY precise does not work.

I'm about ready to chuck this thing against a wall. And we've been so happy together for the last year...
