The phone responded, just the sound was locked. I rebooted and left it alone, came back after a couple hours, phone was HOT and down to half power. Turn it off, pulled batter and let it cool. Popped battery back in, powered up and let it set for 5 minutes, cool as usual. SO I learned Windows Phone lock ups are not always cleared from the processor/memory unless you do a battery pull, as with android a power off is just that, full power down.
Glitches happen and not down on Windows Phone or the Arrive, but a tip to others: if you get a glitch or lock up, PULL THE BATTERY and you should be fine.
