IE6 text wrap issue

I am building a college news site based on the Bernie theme. I have been inserting images in the manage post area by choosing Add Media>Upload from my computer>Caption””>Alignment: Right>Size: Full Size. Then I click Insert into post. The floating works fine in Firefox 2.0, but in IE6 the paragraph the image is inserted into wraps around the float fine, but the next paragraph always clears the float. I have tried manually to fix this in the style sheet with no luck. I have also looked in the codex etc. here is the link to the site I am working on so you can see what I’m talking about.
