I was recently made aware of the problem of SharePoint prompting user to install the ActiveX control name.dll on our public website, www.blue-granite.com, by one of our Microsoft contacts. It isn’t a problem as much as an annoyance to anyone visiting your site when they are prompted. Mossman has a nice fix for it here. While implementing the solution for ourselves as well as for some of our clients, we found the same “gothca” as Michael posted in the comments of this post: “make sure you place a reference on your master page to the init.js file and then declare your override after it, or moss will add a reference to the init.js after your override file and foil all your changes.”
