11092	"""permission denied"" jquery 1.7.1 IE7 on line 1666 accessing elem attribute"	paolo.savoldi.bs@…	paolo.savoldi.bs@gmail.com	"It happens with IE7 (IEtester v. 0.4.8) at this line

id = isNode ? elem[ internalKey ] : elem[ internalKey ] && internalKey

when accessing elem[internalKey].

It seems no elem property is accessible. I detected the error happening when elem is the whole DOMWindow object containing many functions and ajax calls but I wasn't able to isolate the problem. Every other elem in the page doesn't seem to raise exceptions. I added the following workaround to the jquery code

		var privateCache, thisCache, ret,
			internalKey = jQuery.expando,
			getByName = typeof name === ""string"",

			// We have to handle DOM nodes and JS objects differently because IE6-7
			// can't GC object references properly across the DOM-JS boundary
			isNode = elem.nodeType,

			// Only DOM nodes need the global jQuery cache; JS object data is
			// attached directly to the object so GC can occur automatically
			cache = isNode ? jQuery.cache : elem,

			// Only defining an ID for JS objects if its cache already exists allows
			// the code to shortcut on the same path as a DOM node with no cache
			//id = isNode ? elem[ internalKey ] : elem[ internalKey ] && internalKey,
			isEvents = name === ""events"";

			try {
				var id = isNode ? elem[ internalKey ] : elem[ internalKey ] && internalKey;
			} catch(e) {
				// do nothing
