Hi, Randy.  Here's a simple example using a graphic.  Just create a new 
stack, add a line graphic called 'draw', set it's lineSize to 10 then 
put the following script into the card script.  Double click clears the 
drawing, and each mouseDown starts a new line.


local sDrawing

on mouseDoubleUp
    set the points of grc "draw" to empty
end mouseDoubleUp

on mouseDown
    put true into sDrawing
end mouseDown

on mouseMove
    if sDrawing then
       set the points of grc "draw" to the points of grc "draw" & LF & 
the mouseLoc
    end if
end mouseMove

on mouseUp
    put false into sDrawing
    set the points of grc "draw" to the points of grc "draw" & LF & LF
end mouseUp
