// Although the HTML DOM includes an onDblClick event, it's implemented very
// poorly.  Instead of producing one event, it produces three: two click events
// and one double-click event.  This is a problem if we also handle onClick.
// The hack to work around this is to set the click action to work on a short
// timer.  If we get a second click before time is up, we'll cancel the timer,
// and only the double-click fires.  Otherwise we get the timer's click action.
