This occurs in IE8, and IE7. I am not coding to support IE6, so that doesn't concern me.
I have this simple line of jQuery code that runs fine on other browsers, but on IE, I get the error..
Object doesn't support this property or method
I have marked the offending line.
options.button.click(function (e) {
options.menu.is(':visible') ? lift() : drop(); // works fine.
e.stopPropogation(); // error occurs here.
});
