I believe I worked everything out with this one, that I can see. Please look over disable though, I don't want to do anything bad there.

First, you seem to be mixing tabs and spaces or something because your indentation is all out of whack. Second, you seem to be doing things like 'if (foo == true)'. 'if (foo)' should be enough. In the case of 'if (foo == false)', use 'if (!foo)' instead. Your localization strategy is bad. You can't assume you can concatenate user-provided strings like that and have localized things. You also try to use the Shell's localization, which won't work. I don't see why you assign variables to constants, and then not modify them. Just the constants should be fine. Why are you checking the constants instead of the objects when you try to disable them? Have you considered using "else" more? You're also assigning to "this._appMenu". Because this is a global function, you're assigning to the global object. Yay.
