Fixed to work in IE7 and IE8.
Replaced $.browser references with a regex lookup on navigator.userAgent, since $.browser is deprecated in jQuery 1.9.
Fixed a problem where the browser version regex was seeing IE 10 as IE 1.
Attached events to $(document) always, instead of $(windows) for some browsers. Removed the browser detection and switched the event.button to event.which. Thanks to estmatic for the advice!
