I have the same problem but in my case the sizes of the boxes are equal unlike the number of text lines. In the 3rd box the text is shorter that in the others..
Actually I would prefer to hide the text (or at least be able to edit it) and keep only picture and title.
Is that possible? Otherwise I will have to search for another theme..
Is there any way to make page pictures used in the homepage boxes to center on their pages rather than float left? I tried going into the style sheet and using float: center but I don’t really know what I’m doing, and that didn’t work.
