Image Links on Sidebar Not Working

Hi,

I posted this on another thread, but believe that is dead so I wanted to make a new one:

Please see this page:

http://www.wgel.net

The top ad on the right sidebar should be linked, however only the top part of the image is clickable.

If I move that widget down to the bottom, the entire image becomes clickable. The HTML appears to be correct.

I’ve tried to work around this with an image map, but that doesn’t work either. There must be some class or something that is causing this? Please help, we are to make this site live in 2 days but we are in trouble if the ads are not fully clickable.

Thanks,
Dan
