You need to add in the origin offset of the world's FormCanvas when you 
draw upon it directly through its GrafPort, otherwise you are Blitting 
your red rectangle starting at the origin of the Display, rather than the 
origin of the Morphic window.

Should be something like:

     copyFrom: buff boundingBox
     in: buff
     to: ((destRectangle origin) translateBy: self origin).

When I do that, the rectangle is always red, as I think you are expecting.

Thanks - that did the trick.
