As the mousemove handler is not suspended in Revolution when choosing
a graphic, paint or pointer tool, there is still another way to do this.
In this example the canvas is outside of the field.
Set  the script of the card to:

on mousemove
   if the mouseloc is  within the rect of fld "border" then set the 
cantmodify of this stack to true
   else set the cantmodify of this stack to false
end mousemove

### if the mouse leaves the card and/or if the "border" field is flush 
with or passing the sides of the card
on mouseleave
   if the short name of the target is in "card id < id of your card 
 >,border" then set the cantmodify of this stack to false
end mouseleave
