[Newbies] window collapse and remain on world?

Seems to me it used to be that when you clicked on the little circle at the right on the top bar of an open window, the window would collapse to a small icon on the World showing the window title, usually at the upper left somewhere. Now in sq3.10.2-7179dev08.11.1 it appears this has been replaced by the window collapsing to the task bar at the bottom. I'm not sure at what pint this started working this way.

Is there any way to be able to selectively decide whether you want the window to collapse and remain visible on the world, collapse to the task bar, or perhaps both?

Thx, Ken G. Brown
