Yes, doesn't fix the issue.
When I turn on my monitors, the single dock I have defined is on the primary monitor. The settings say it is on Monitor 3. I have to change it to Primary and back to Monitor 3 to move it to the correct monitor.
Re-starting or rebooting keeps the dock on the correct monitor. Power cycling the monitors moves the dock to the primary monitor (although it reports it is on Monitor 3).
thanks,
Chris
