Here is my webpage: http://188.8.131.52/~thomasse/
The "TSI" logo at the top left of the page used to get lighter when you mouseover it. You can see the same effect on the nav menu items, and here on this logo ( http://www.elegantthemes.com/preview/SimplePress/ ). For whatever reason, this is no longer working on my page. Any thoughts? I have tried a lot of changes in the css to no avail.
