When i have the Clipmarks (http://clipmarks.com) extension activated, all new and editet posts or pages get messed up and break the blog, making it unusable.
For whatever reason a block like
<div id="Clipmarks329BorderDiv209" style="border: 2px solid orange; margin: 0px; padding: 0px; position: absolute; width: 0px; display: none; z-index: 99999" />
<div id="Clipmarks749BorderDiv7077" style="border: 2px solid orange; margin: 0px; padding: 0px; position: absolute; width: 0px; display: none; z-index: 99999" />
<div id="Clipmarks957BorderDiv1047" style="border: 2px solid orange; margin: 0px; padding: 0px; position: absolute; height: 0px; display: none; z-index: 99999" />
<div id="Clipmarks287BorderDiv1781" style="border: 2px solid orange; margin: 0px; padding: 0px; position: absolute; height: 0px; display: none; z-index: 99999" />
gets appended to every post or page i edit - this can be seen when switching to HTML view.
