Subcategories & sub-subcategories page links are stacking

Hi all,
I have a new problem... on the subcategories pages and the sub-subcategories pages, the links and their logos are displayed stacking on top of each other instead of being spread out in three columns. The just happened all of a sudden, they were displayed fine a day or two ago... Could someone tell me what setting in the Admin is causing this? Here's a link to one of the subcategory pages for reference, followed by the page code for that layout... thanks... METOOTECH...

everything looked fine to me.....with IE7

Okay as well.. with FF.

However on the product listing pages, I will note that items that are sold out.. the CSS "Sold Out" button covers the "More Info" link. Methinks a button image wouldn't even work, I guess there's just not much room within the custom grid.
