In order to catch the user escaping the button without making any choices this
works:
local lLabel
on mouseDown
put the label of me into lLabel
end mouseDown
on mouseLeave
if lLabel is not empty then
if label of me = lLabel then
answer "You did not select anything"
put empty into lLabel
end if
end if
end mouseLeave
