Jeremy, ok I am on the same page as you. I just thought there was something else I was missing. My MapManager.mxml is set up like yours. And my logo works fine and I do not see the ESRI logo at all, but yes both my link and ESRI opens at the same time. We were getting much forum love on this at first, but it seems as if people are not sure as to why both links would still open?! I guess its better than nothing that my logo is there and my link opens, just dont really need to ESRI link to open with it.
