mouseDown and within

[Eric Chatonet]

Hi Tom,

Menus are handled by the engine and unfortunately are not transcript 
statements :-( or :-)
Something like that (non tested) in the card script:

on mouseDown
   if "button" is in the target then
     CheckOtherButtons -- Æ
   end if
end mouseDown
---------------------------------------
on CheckOtherButtons
   if the mouse is up then exit CheckOtherButtons
   repeat with i = 1 to the number of btns
     if the mouseLoc is within the rect of btn i then
       set the hilite of btn i to true
   end repeat
   send "CheckOtherButtons" to me in 50 milliseconds
end CheckOtherButtons

But I would to turn your attention to another thing: I'm not sure such 
a behaviour is good ergonomics...
Best regards from Paris.
