I closed the program and yet continued hearing chatter.

Opened Task Manager and there were two instances of the program running.

One had 515 mb, the other had 60 mb.

Right clicking the shortcut does not show a choice of 'close window' 

If I then click the shortcut the program opens normally. When I click to close the two shards remain.

 

Maybe dependent on minimize/maximize P2A with button or key ?

A minute ago after closing P3D with P2A window hidden (forgot it after aircraft shutdown), I couldn't reopen it by clicking on it.
After right click on the task bar icon of the initial P2A instance, strangely a second instance starts up, I closed it.

Then I pressed my HOTAS button and the initial P2A instance came up, so I could close it.
Btw: in the initial instance, the MAP and COMM window were disabled, don't know if this matters.

It should close properly in the next release 0.1.6.

Thanks,

Dave
