The default behavior of a Popup is if it is placed where it would extend beyond the edge of the screen, the Popup will reposition itself. Is there a way to turn this behavio
If you want the popup to behave more like a Window, I'd just make a Window instead of a Popup.
Having a popup that doesn't position itself like a standard popup, and allows you to drag it around the screen, just seems like a recipe for low usability and confusion.
