I've 2 IE7 bugs on the site I am doing. http://tinyurl.com/88jbgug

Around the nav bar, I recieve an over stretching nav bar that does not appear to reply to overflow: hidden, and I am not sure I understand which bug I am coping with.

As well as on the modules I think I've the double margin bug but I am not sure regarding the way i can eliminate it.

Its a Joomla site running on xhtml 1. transitional.
