Hi Lee
I just saw how old is original post... sorry if it is not actual anymore
Anyway, another method for double-click for your example
(action_tile "accept" "(done_dialog)")
(action_tile "LB1" "(if (= $reason 4)
(alert (nth (atoi $value) mylist))
(setq ptr $value))")
(action_tile "cancel" "(done_dialog)")
Note that is working no matter how allow_accept is set..
