Hi Craig,
I've had this before. I found that there is some CSS generated on the results page that resides in the head of the document. One of these rules is:
.WADAResultsTable {
font-size: 11px;
clear: both;
padding-top: 5px;
padding-bottom: 10px;
}
I find that changing clear: both; to either left or right (depending on which side the sidebar is) fixes it for me.
Hope that helps.
