blocking button hilite

Hi Charles,

All questions always make sense.
Some answers no :-)

Have a look at the autoHilite property and set it to false (there is  
a checkbox in the property inspector).
Then script mouseDown, mouseUp and mouseRelease handlers according to  
you needs.

Normal behaviour:

on mouseDown > visited = false (or true)
on mouseUp > visited = true

So check the visited property on mouseDown and set a flag to act  
within the mouseUp handler:

local lVisitedFlag
---------------------------
on mouseDown
   put the visited of me into lVisitedFlag
end mouseDown
---------------------------
on mouseUp
   if lVisitedFlag then...
   else...
end mouseUp
