When I save to flash, power cycle and reconnect to the Espruino IDE
Ok, so are you sure that after you've saved to flash, you then tried to connect with windows Add Device?
Add Device
Because if you saved to RAM and power cycled the Puck would have lost your code, so that's about what you'd expect.
