[fixed] Window docking doesn't work for multiple monitors system

[micheus]

Thanks for the detailed information. I could check these issues.

apparently, docking behavior doesn't work on a secondary monitor(?)

Yes. I'm going to verify if it's something we can act to fix or if it's a wxwidgets library issue.

fyi, in a moment of perversity, I had my secondary monitor in portrait mode, (no space, O.K.??? which seemed to cause the context menu, (or secondary popups, like the Absolute/Move dialog), to pop up lower and lower, and eventually off screen.

You are bad.
Yeah, I could noticed that. For me, it seemed that dialogs are always displayed in the primary monitor.
