As an alternative, you could insert the following (untested) script into the
frontScripts on preOpenStack:
local lTarget,lCondition
on mouseDown
put the long id of the target into lTarget
if word 1 of lTarget is not "button" then pass mouseDown
put (the icon of lTarget is 0 and the hiliteIcon of lTarget is not 0) into
lCondition
if lCondition then set the showIcon of lTarget to true
pass mouseDown
end mouseDown
on mouseUp
if word 1 of lTarget is not "button" then pass mouseUp
if lCondition then set the showIcon of lTarget to false
pass mouseUp
end mouseUp
on mouseRelease
if word 1 of lTarget is not "button" then pass mouseRelease
if lCondition then set the showIcon of lTarget to false
pass mouseRelease
end mouseRelease
The above script would have the disadvantage that the display of the
hiliteIcon wouldn't track the mouse movement while the mouse is held down
and moved outwith the button (that could be added in if necessary). However,
you might find this a satisfactory temporary solution until the MC bug is
fixed. Then you could simply not insert these handlers. On the other hand if
you've just got a couple of buttons, one of the workarounds you suggested
would be better!
