windows in windows in menubars

[EMaude]

I can open widows of this program inside windows of this program. I can then hide these windows inside other windows inside the main window. I can also put those windows inside the menu bar and pull them back out.
Here are 25 windows of this program running inside 1.

This was done through settings -> update phratch view -> then no to prompt

On the screen I see a pharo 2.
Could you provide the version number ? I am thinking it is an old one.
