[plt-scheme] IE Warnings

Sorry - just got this. Should've read your original post more carefully.

> Yes, that's the solution that I described in the original post.  The
> problem is that once you fake a lower zone like that, links from it to
> a higher zone don't work (silently, to get maximum annoyance factor).
> So you need to add these comments on *all* html pages, so the target
> link will also be considered in the same zone ("Internet").  But if
> there's a link to something that is not an html file (like the release
> notes text files), then there's no way to add that comment, and these
> links will just not work.  That makes things considerabley worse.
