But I ran into an issue (maybe this is Windows (10) specific):

once I open the window, the original Pharo window is no longer responsive. It is not frozen, I can see a cursor blinking in the playground, but clicking anywhere or pressing any key doesn't do anything.

This behavior persists even after I close the new window.

Only when I press ctrl (without anything else) the content of the playground gets executed again, but that's it.

I will try tomorrow on a different machine.
