ThankU, I'm glad you mentioned the removing the group, because once I get
the circls drawn on to the canvas, when for example the user zooms_In to a
particular area, I dnt want to zoomIn into the red circls so I was
thinking when you zoomIn to remove the 'circleGroup' and add them in
again...what do you think????
Many thx
