After the player starts up, if you crank the volume knob down/up it is very slow in response. I can literally turn the knob down, let go, and watch the volume go down slowly for 3-4 seconds. After all of the “queued up” buttons finish, everything is normal.

I had this happen the other day, actually. I tried to reproduce it with no luck, so I just chalked it up to a stray gamma ray or something.

*sniff sniff* smells like a bug...
