"Only allow one FX window open at a time"

[Rangler]

When I drag to a plugin to another track, it opens another plugin window and closes the previous window even though I turned all of that off in preferences.

Not only does it open a new FX window, it repositions the window down and right a bit. I don't want my windows migrating all over the screen, esp when I turn it off in preferences.

Thanks for the look/see.
