Okay I tried that

|form rect|
rect _ (SchemeView example2).
form _ FormCanvas extent: rect extent.
rect drawOnCanvas: form.
	[Sensor anyButtonPressed]
		whileFalse: [
form showAt: Sensor cursorPoint]

I can move the form around in no time. Nice. But of course is destroys
my background. Are you aware of any code I could steel ideas from for
fast dragging. (This is NOT the animation issue but the dragging issue
from an earlier thread)
