I think I understand your first message better than the "more complete"
followup. :)
I can't follow what you are suggesting about the field-under-an-image.

Hi,

I mean an image on top of a field.

Some changes to avoid the problem caused by  the transparency
and the opaque condition of the image (which can crash the app
occasionally or often)
The field will catch the mousemove as the image gets  a transparent 
condition
when drawing only one pixel.
As there is still an unresolved bug with the select tool it is not 
usable
in this handler.
The spray can tool is tricky too, but can be used with this change.
In revolution the erasor tool and the spray can tool will not show 
their icon
 when chosen by script, in metacard they do.
(when using drawing tools, the overhead in revolution is enormous 
compared to metacard)

Make the image and the "underlying" field the same size.
Set the scripts of both to (I know its kind of dirty but is simple and 
only for demo):

on mousemove
  if the mouseloc is within the rect of img "xxx"  then
    if the mouse is not down then
     put the hilitedbuttonname of group "tool" into a
     if a is "spray can" then choose spray can tool
      else  choose  a  tool
      checkformousewithin
    end if
  end if
end mousemove
and set the script of the card to:

on checkformousewithin
  if  the mouseloc is within the rect of img "xxx" or the mouse is down 
then
    send "checkformousewithin" to me in 100 millisecs
  else
    choose browse tool
  end if
end checkformousewithin

Greetings,
WA
