Again, since it's a freeze, rather than a snap, the window won't just
sit there jumping back and forth.
Though if the range between boundaries is close enough, you _will_ get a
quantum movement effect -- the window will "want" to be at one position
or the other. But you need to make a significant mouse displacement (at
least equal to the boundary setting) for this to happen.
Also, looking at the dialog, edge resistance can be a "resist" (what
I've described) or "attract" (leading to pinballing).

Nope. Because impede doesn't move the window. It stops it. Moving
past the boundary overrides the behavior. Just tried this both ways.

What Part of "Gestalt" don't you understand?
First they came for the Communists, and I didn't speak up, because I
wasn't a Communist. Then they came for the Jews, and I didn't speak
up, because I wasn't a Jew. Then they came for the Catholics, and I
didn't speak up, because I was a Protestant. Then they came for me,
and by that time there was no one left to speak up for me.
