When I create a post now, unless I manually set the title in the AIOSEOP metabox on the page, the browser title for the post (from <title> tag) is now "Real titleBLOG NAME | BLOG NAME" instead of "Real title | BLOG NAME." I don't know why the blog title is appearing twice, but I would really like to fix this if anyone knows how.
Thanks,
Scott

Update: Same issue here: http://semperfiwebdesign.com/forum/all-in-one-seo-pack-troubleshooting/rogue-site-title-in-post-headers/. New version supposed to be coming out soon that fixes compatibility issue with TwentyTen.
