[Plugin: Boxer] Boxes Don't Display Properly

I can’t seem to get boxes to display properly. If I set the boxes for three across, two display in the first row and one displays beneath. If I set them for half across, they display one on top of the other. If I set them to display four across and only have three boxes in the set, three boxes will be displayed across. However if I add a fourth box, it will display in the second row.

It’s driving me crazy.

Additionally, I thought I might try upgrading to the Pro version, but I wasn’t much into having to pay $20.00 for a plugin you advertise on your site for $12.00. It’s not so much the extra $8.00 I would have to deposit, just the principle.
