Skinny blocks "Edit Block" option breaks ability to click links

I guess my columns are too skinny, but the "Edit Block" option creates an invisible "panel" flowing all the way down the page from it that doesn't allow me to click links in adjacent columns. For example, in the attached image I cannot click on the first half of the "Comments" link, nor the word "Hide".

It's not been a huge problem, and I'm probably going to make my columns larger because other blocks (like "Search," etc.) are broken by the skinny columns, but just wanted to point it out.

The column in question is a Span-5 class.

Thanks!
