      Thanks for the quick response and the fix. I will load 8.7.6 tonight and try it out.

      yes, the LCD was just frozen - the clock was going on but you could not see it. We have updated to 8.7.6 - blank screen issue after charge is now fixed. Firmware posted to http://emotorwerks.com/JuiceBox_Public/8.7/50%20-%20Firmware/, as usual

      ;-) did not survive the last round of memory usage optimizations...

      Thanks Val... the power fail issue happened after the 8.7.5 update while I was testing to confirm the blank screen issue. Just a power-in unplug/plug cycle with car still attached. I noticed the clock stopped because power outage was maybe 30 seconds while clock just froze for tens of minutes until I unplugged from car, power cycled JB, plugged car back in. Yes, it could be just a non-updating LCD... the "READY - | -" was not updating either. What happened to "/" ? :-)

      thank you Gregg - we have confirmed blank screen bug. It does not affect operation but is annoying. We are fixing it for 8.7.6 to be released tomorrow (Sunday April 6). Could you please describe the lock-up issue? How short is the power interruption? If just a couple of seconds, this may be caused by display reset without Arduino reset. That would result in blank screen but operating JuiceBox. Please note that time keeping precision is not guaranteed upon input power interruption.

      8.7.5 has the same odd behavior as 8.7.4 - at least on a premium with wifi and 8.6 board. After a car terminates the charge, the LCD screen is blank and stays blank until you unplug from vehicle. Also, the JB locks up (and stops keeping time) if there is a short power failure while a vehicle is done charging but still plugged in. Premium users: you may want to hold off on updating for a stable rev..
