after leaving a Remote Desktop session, where I arranged the pharo image windows on the desktop,
and re- entering the in a new remote Desktop session, the pharo image windows are all in the middle of the screen.

Example:

I arrange the pharo image windows like this:

then I leave the session.
I enter in a new session.
The pharo image windows are alll in the center of the screen.

I wish that the pharo image windows would remember their position.
