Firefox not showing focused radio or check boxes

[Pontiac]

Binary package hint: firefox-3.0

When displaying google.com (Or any web site that uses radio or check boxes) when the box is highlight, the selected object seems to become hidden, or placed underneath a solid square. I checked with any application within KDE and noted that the check boxes appear to be working. Attached screen shots. The image on the left shows a square box next to "the web" but its actually a selected radio button. When looking at the KDE Control Module, the "Blinking Cursor" check box highlights as blue. It'd be normal to expect to be able to see what you've selected as being checked on or off.

I should note that in Konquerer, this "hidden button" doesn't seem to be present.
