Generic llDialog menu handler for Linden Scripting Language (LSL). Insert into the top of your LSL script.

llSetTimerEvent is used to control lag by shutting down the listen after 60 seconds. You must add

llSetTimer(0.0);
llListenRemove(handle_dlg);

to the timer() event to use this functionality. The llSetTimerEvent(60.0) may be removed otherwise.
