Sadly, I've found window class IDs to not be very unique (though I've
looked mostly in Wine and not Windows).

A long time ago (Win2K era) I wrote an application for Windows that replaced the text everywhere (that wouldn't crash the OS) with "All Your Base Are Belong To Us."� At least at the time, you could rely on the window class to differentiate between different types of windows (dialogs vs. menus vs. different types of controls).� Taking advantage of this behavior was especially important in IE, which would crash the whole OS if you changed the text of any of its menus.
