JUst wondering if this was resolved? I have the exact same thing happen...Flirc working perfectly for a really long time, 6-8+ months at least...firmware in Flirc was 2.6.
I'm using OpenElec XBMC in a Intel NUC. XBMC is Frodo 13.2, and I don't think it's updated for a while either. A few days ago, for no reason, XBMC starts going nuts like a key press is stuck...I had to turn off the device. When it came back on the Flirc wouldn't work any more. Hooked Flirc up to my laptop with Windows 7 and updated firmware from 2.6 to 3.1. Then I clicked 'Go' in the Flirc software and pushed the buttons to memorize them on my silver Apple remote. The key recording isn't sticking, I can't get it to remember the keys now :(
Any help is much appreciated.
