CSS rules: body{ background-image:url('/images/test.jpg'); background-repeat:repeat-y; }

These rules give the page an image, tiled down the page only (instead of down and across), on the left hand side. This is the link to the page unmodified. Click on this link to see the page in a google frame (hopefully exhibiting the bug: if you don't see lots of funkiness, reload the page once you're in the frame). Read my blog post about this.
