Perhaps you could just create an object and trap the mouseLeave message and
move the pointer in that?

I found that using a "send in time" structure to check the mouseLoc
rather than waiting for the mouseMove message was slightly more
reliable (OSX) and better kept it from going outside the bounding area.
on MouseTrap
-- keep the mouse pointer inside the window
if the optionkey is NOT "down" then -- but overide this behavior
with the "optionKey"
put item 1 of globalLoc(the mouseLoc) into x
put item 2 of globalLoc(the mouseLoc) into y
put the top of this stack into tTopEdge
put the bottom of this stack into tBottomEdge
put the right of this stack into tRightEdge
put the left of this stack into tLeftEdge
if x < tLeftEdge then put tLeftEdge +1 into x
if x > tRightEdge then put tRightEdge -1 into x
if y < tTopEdge then put tTopEdge +1 into y
if y > tBottomEdge then put tBottomEdge-1 into y
set the screenmouseloc to x,y
end if
send MouseTrap to me in 40 millisec
end MouseTrap

This script seems to work with adequate performance:
on mousemove mh,mv
if the hilite of btn "constrain" is true then
if mh <= the left of fld "container" then
set the screenmouseloc to the globalloc of (the left of fld
"container", mv)
end if
if mh >= the right of fld "container" then
set the screenmouseloc to the globalloc of (the right of fld
"container", mv)
end if
if mv <= the top of fld "container" then
set the screenmouseloc to the globalloc of (mh,the top of fld
"container")
end if
if mv >= the bottom of fld "container" then
set the screenmouseloc to the globalloc of (mh,the bottom of fld
"container")
end if
end if
end mousemove
Note two things:
1) The button "Constrain" needs to be within the field "Container"
or you'll
never be able to get out. :-)
2) It is possible to move the mouse out of the rect for brief
moments, but
then it pops back into the rectangle. I'm assuming it's a function of
slipping out between a mousemove scan.
