What I wound up doing was this...
Delete Audio/MIDI Preferences.
Make a new Aggregate device even though it really was just the Main out of the computer.
Back in DP I deleted all the Bundles that I wasn't using and reset all ins and outs.
Now DP 8.05 seems to be behaving like it is supposed to. I can close and reopen without the mute bug showing up. My guess is the Audio/MIDI preferences were corrupted.
Thanks for all the input.
Back to having fun with DP8!
