1. Create a new page
2. Edit the page and paste this into the wiki markup tab

{html}
<iframe src='http://wiki.riptown.com/applications/ResourceLocator/Seymour10.svg' height='674' width='1124' FRAMEBORDER=0 NOBORDER />{html}

3. click save
4. click the edit tab
5. look at what it has on the rich text editor
6. click on the wiki markup tab
7. look at what it has on this tab

Its now impossible to edit the page properly. The only workaround I found was to set the Wiki Markup tab as the users default, that way when you click the edit tab the wysisyg editor doesn't screw up the html macro before you can edit it.
