The problem is that when the meta tags are inserted, for whatever reason our style sheets stop working on those files. As an example, when we import files into a project that were in a v7 project, it inserts all these new Robo9 meta tags. Then, the style sheets for those files no longer work until we go in and delete all those new tags.
That's curious. Which meta tags are giving you problems? I can think of a few tags that interfere with the browser rendering mode, but that normally means that you need to update your CSS.
