RJ,
I think we have a winner.
I had one channel, on one of the LEs acting funny right out of the chute. It was flashing a lot by itself, way more than before. After a power off/on, still there. I actually went in and flashed another Wireless module, and got caught up with some visitors for the display and did not get it put into the box. I then noticed that it was behaving fine all by itself and did not have to put the re-flashed unit in.
After the show tonight, I let channels sit where I could watch them. Not a flicker at all.
I REALLY appreciate you getting that firmware updated.
