I haven't kept a real close track of this problem, for the simple reason that the bug doesn't coincide with the way I use the 990. I didn't come across it when experimenting with the 3.10/3.11 update, either, but I don't know that I did much of anything with bypass mode at the time. I do know that Scott's on the case. It's possible that they're having to involve Etronics engineers in some of it, and based on what I've seen in a thread at AVS about Sherwood's new receivers (Sherwood being Etronics' "house brand") that may be time-consuming. Scott may be able to offer some further insight on this one, as he tends to be the central person for these sorts of processes, but he is probably on his way to Colorado at the moment for RMAF. Maybe next week we can find out something more.
