Since the properties of the arc is available even if it is invisible, this will work though:

on mouseDown

put isWithin("myGraphic",the clickLoc)

end mouseDown


function isWithin pGraphic pClickLoc

if pClickLoc is within the rect of grc pGraphic then

return true

else

return false

end if

end isWithin
