Simple patch. The current state of checkbox descriptions looks something like this: http://cl.ly/image/1u0W11180x3i. While visually it's not covering the checbox, the div is larger due to the tail arrow thing on the bottom. This leaves about 3px for you to click on the checkbox. Patch below changes it to this: http://cl.ly/image/1g0D0X2o3R43. Much more clicking room.
