CSS fix for InfiniteGraffiti.com

If you look at [login to view URL], you'll see a little paintcan at the bottom that *should* look like it's full of white paint. When the paintcan is clicked, a color dialog pops up, allowing the user to change the color, which should then change the color inside the paintcan. In Chrome it just about works, but FF shows the inner paint -- a rectangle of color -- off to the side. I want this to be worky in all browsers -- and layering divs is the hardest thing for me in the world. Note that it's inside a table cell, and I want it to STAY inside a table cell. For my own sanity. Please don't whine about how tables aren't for design or layout. I've heard it all.
