I have a site that uses AJAX to navigate. I have two pages that I use a click and drag feature using
$(\".myDragArea\").mousedown(function(){ do stuff...
Calling $("body").mouseup(function) will add an event handler. You need to remove the existing handler by writing $("body").unbind('mouseup');.
$("body").mouseup(function)
$("body").unbind('mouseup');
