Block nav elements collapse when they are clicked

Any idea what might cause this?

It's a mix of tables and CSS. The text menu utilizes block elements and looks fine when it first displays. When the text menu links are clicked they all run together as they are clicked.

We go from this (lines (______¦) represent the edge of the table cell) below when none of the links have been clicked

whenever the links are clicked. Never seen this before, any idea what might cause it to happen?

It certainly sounds like the block display is being negated by a value in the :visited style. That, or possibly the application of absolute positioning, but more reasonably the former. Are any of the link states using any form of display other than block?
