RE: problem ?
Okay I admit that I didn't really think I'd really get off that easy, but I had to start from somewhere.
It definitely sounds like a comms problem, although it's a little early to blame it on the ECU- does it make any difference if the Tx is not turned on? (What freq are you guys flying on "Down Under" anyways, 35Megs?)
After you've cycled the ECU power does the problem go away, or does it just take you back into the first screen (until you press the menu button again...)
