IN this, Geoff Canyon says:

on mouseDown
    put true into tDragging
end mouseDown
on mouseMove mouseX,mouseY
    if tDragging then
-- Do bounds checking here --
        set the loc of me to (mouseX,mouseY)
    end if
end mouseMove
on mouseUp
    stopDragging
end mouseUp
on mouseRelease
    stopDragging
end mouseRelease
on stopDragging
    put false into tDragging
end stopDragging
IMHO, the **only** reason to use a scheme like this is in order to 
constrain the dragged object completely, i.e. so that the user can't 
move the object out of some chosen bounds (say a particular 
rectangle) even while dragging. If Monte is content to allow the user 
to drag an object anywhere in a window and then apply the constraints 
when the user lets go of the mouse (giving a kind of rubber-band 
effect, which can look quite attractive in some circumstances), then 
it seems to me that there is only one elegant solution, which is to 
use 'grab me' - it's built in and it's very concise. In the 
'rubber-band' case, I can't see any need for any other solution.

Just two more Eurocents
