I have had a couple of people mention this nuance on our site and so I've spent a good part of the morning trying to figure this out.  At the top of both our LeftPane and ContentPane we are getting an extra space inserted.  I've gone through our skin and container files as well as used the IE Developer Toolbar and Firebug.

What I can see with the tools at hand is that there is a line being added for an extra break tag at the top of every module.  I would assume this is something DNN is adding since it is no where in my skin.  Any idea where I can find this culprit?  We would like to minimize the whitespace between our breadcrumb/search bar and the content.

I started thinking about it after you posted and went back and looked at the container skin again.  The skin file itself didn't have any TBODY tags which were being added by DNN.  I manually added these in, and changed a couple of the cellpads and voilà, all is better.

Thank you for the reply your input helped point me in the right direction.
