[squeak-dev] systemWindowEmbedOK was: Morphs can be dropped on main docking bar

For SystemWindows there is already a preference called „systemWindowEmbedOK: Determines whether, in Morphic, when a SystemWindow or MenuMorph is dropped onto a willing receptor, it should be deposited into that receptor.“

If this is disabled at least browsers cannot accidentially be dragged into the docking bar. I think this preference should be disabled by default. What do you think?
