On IE, localStorage does not work with the "file:///" protocol.
If you want to polyfill it, you must avoid direct assignment of window.localStorage.
Instead, you must use "Object.defineProperty()", like this:

window.localStorage = 'hello';
alert(window.localStorage); // undefined
Object.defineProperty(window, 'localStorage', {value:'hello'});
alert(window.localStorage); // hello

As a side note, I think only the Flash technique works in IE Offline

I get the error 'Unable to get property getItem of undefined or null reference' when compiled into a chm. However the same code when packaged as an MSHC works properly. Despite both HH and Help Viewer 2.3 both use IE7.

Safari private browsing disables localStorage but also makes window.localStorage readonly, inconveniently. What's the best workaround for this?
