Firefox 1.0.7 Flicker Bug
These modules use the overflow:auto; hack to ensure the containers clear the floated elements inside. The text links are defined with :hover {font-weight:bold;}. Removing either the overflow or font-weight properties cure this bug. However both are needed either to make the page work or to meet the design requirements.
This bug is not present in Firefox 1.5.
Text example
Move your cursor over any of the links, on the page and keep an eye out for the flicker effect.
