In an exciting turn of events, I'm pretty sure I've tracked down the weird USB
reset glitch that was a remaining gremlin after I cleared up my RAM issue. There
is little bit of drama still unfolding as part of this solution, so I'll save
the full story for when that's resolved, but in the meantime I wanted to share
my happiness that this is being worked out.
it could also be something as dumb as 'touch this piece - buzz - correct piece'. move here - buzz - correct move. he could totally play it off as evaluating possibilities. you can move pieces around like that as long as you don't let go of them.
