This directory has some files related to mozilla bug 229734. test.html is a test showing the problem. the files cor-tl.png and cor-br.png are used to create the cropped corner effect on the divs in the page. By resizing the browser window, you'll notice that a single pixel line appears beneath the bottom right corner in some circumstances. It appears to be either an issue related to how far down the screen the bottom appears or due to the size of the box it goes in.

The screenshots are several demonstrations of the problem occuring on my computer.
