Your e-mail is in line with my understanding. In HTML5, the "inner window" is the Window object and the "outer window" is the WindowProxy object. With one minor exception to do with about:blank, there's a 1:1 mapping from Document to Window, and a 1:1 mapping from WindowProxy to browsing context. Each browsing context can have many Window/Document pairs. For what it's worth, right now HTML5 says: If the script's global object is a Window object, then in JavaScript, the |this| keyword in the global scope must return the Window object's WindowProxy object. This is a willful violation of the JavaScript specification current at the time of writing (ECMAScript edition 3). The JavaScript specification requires that the this keyword in the global scope return the global object, but this is not compatible with the security design prevalent in implementations as specified herein. [ECMA262] I'd love to be able to include this requirement without it being a violation of another spec. HTH, -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
