Re: ProgRock Serial - flickering led

If I switch off power to the ProgRock, led goes back to flashing dimly.  Power to ProgRock on again, gets the appropriate response again.
Anyone know what's going on?  Does it represent a danger to arduino or ProgRock?
Seems typical of where a small current flows back through a high data line.
Probably so small it has no effect but one tends to think it's best to avoid the situation.
