Floating Menus in IE

I am completely fed up with Internet Explorer. I am using a seperate CSS file for Internet Explorer, trying to get the floating menus on my live test block/backlog to get in the places they should be. The menus look fine in Firefox, which is wonderful, but I want them to also look right in IE.

If push comes to shove, I’ll just try creating a different menu layout without the floats.

Anyway, I was wondering if any of you could take a look at the CSS and give me so idea of what you think the problem is. I am using this particular layout as a learning experience…which it is really turning out to be.
