Hi all, I have written an IE browser sidebar, which in turn hosts an instance of the WebBrowser Control. (The extension is written in C++). What is the correct way to detect when it is being activated by the user? I had thought IObjectWithSite::SetSite was the right place, but that seems to be called as soon as IE opens. What I want is some hook for when the user activates the sidebar, either from the menu or the button I've installed. Thanks very much, Malcolm Pollack
