Hi ,

Thanks , so nearly - I have a line that follows the object from the top left corner.

What I need is just like drawing with a pen , the object being the tip. Where the object moves a line is drawn and remains like ink.

Not sure what you really want, but maybe try this. On a new card create a
button and a line graphic. Put this into the button script:

on mouseDown
end mouseDown

on trackButton
   if the optionKey is down then exit to top -- exit here
   set the loc of btn 1 to the mouseLoc
   set the points of grc 1 to "10,10" & return & item 1 of the loc of btn 1
& "," & item 2 of the loc of btn 1
   send "trackButton" to me in 1
end trackButton
