Lardman,
Thank you.
To this thread, I reflashed the Z with the latest OSPACK and then reflashed OZ. That is working much better. Most of the light and touch screen anomalies seem to be resolved. As Sam noted in another thread, OSPACK flashes deeper in the stack. OZ is dependent on this flash.
To anyone reading this thread, if a Z is intermittent try flashing with a late OSPACK and then reflash OZ.
