Hi Charles,

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

Is there a way to prevent a button from being hilited when clicked? I want to put hilite under script control, but the toggling of hilite happens before the mouseUp handler is entered.

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.

Also, more or less the same question about the "visited" property. I can set it false for all buttons in an openCard handler -- but as soon as one is clicked, before its mouseUp handler is called, the button's "visited" is already set to true. So how can I tell within a button's mouseUp handler whether it's been clicked before? (If it has been, I want to prevent the hilite from toggling back and forth, and also prevent a "tasks to do" counter from being decremented.)

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
