To do it with this method, the traversal of the field needs to be off.
(though this can probably be worked around)
Put this script into the field.
local sMouseLoc
on mouseDown
put the mouseloc into sMouseLoc
setScroll
end mouseDown
on setScroll
if the mouse is down then
lock screen
if item 1 of sMouseLoc > item 1 of the mouseloc then
set the hscroll of me to the hscroll of me - (item 1 of the
mouseloc - item 1 of sMouseLoc)
else
set the hscroll of me to the hscroll of me + (item 1 of sMouseLoc
- item 1 of the mouseloc)
end if
if item 2 of sMouseLoc > item 2 of the mouseloc then
set the vscroll of me to the vscroll of me - (item 2 of the
mouseloc - item 2 of sMouseLoc)
else
set the vscroll of me to the vscroll of me + (item 2 of sMouseLoc
- item 2 of the mouseloc)
end if
put the mouseloc into sMouseLoc
send setScroll to me in 50 millisec
unlock screen
else
put empty into sMouseLoc
end if
end setScroll
