Switching Maestro batteries using AC brick for holdover causes Maestro to stop

New to Flex and Maestro so maybe this is operator error. I have 2 Mogix batteries. When one battery nears exhaustion, I connect the Maestro to AC power via the supplied power brick. I then disconnect the exhausted Mogix and connect the fully charged Mogix. AC brick is used for holdover during the switch. All goes well to this point. The issue arises when I  dosconnect the AC power brick from the back of the Maestro (12V DC coaxial connector). 

At that  point, the right side of the Maestro goes dark (buttoms), the display freezes and a short time later a Windows dialog box pops up stating "Maestro has stopped working... Check online for a solution... Close the program... View problem details."

I believe the internal battery can be used for holdover but having the AC brick handy, I plug it in to avoid internal battery exhaustion so as to not interrupt any QSOs. It seems that once the brick is plugged in, there is no way to  transition to external battery.

Running V2.2.8.40.  Maestro SN 2118-3389-0100-1234 (power button on side).

IIRC using the AC Brick disconnects the battery input

So you should not have the brick connected when switching batteries as the internal battery will easily hold the radio while you switch batteries

So once the Maestro is connected to 12VDC via the coaxial connector (via battery or AC brick) there is no way to transition to USB power pack only power. So if I normally have the Maestro connected in the shack to 12VDC, there is no way to then move the Maestro to a different location in the house via USB power without interrupting operation. 

So if one plans to move the Maestro around in the house, one should never connect power via the 12VDC coaxial connector but rely solely on USB power packs. Of course, if one wants to shut down the Maestro in the interim, no issues.

You are incorrect.  Connect the battery and unplug the coaxial power connector.

Tim, On several occasions per the my original post in this thread I had the Windows "Maestro has stopped working" dialog box pop up. I will try and recreate that scenario.

I did just execute the following sequence with no adverse effects other than the right side lights and the speaker go out briefly after pulling the coaxial connector

If I continue to have issues I will try and reconstruct the scenario and update the thread.

Thanks,
Ron

Correct.  When you change power sources, the Maestro is temporarily powered from the internal display battery.  The software does a search for a valid power source and once it finds one, it uses that source and runs the power management logic associated with that source.
