CSS Inheritance - Confusing IE Behaviour

[ADAM Web Design]

I've used this menu system I've created 3 times now and this is the first time it's ever posed an issue:

http://www.kastlefireplace.com/newlayout/test.html

In the second tier of the menus, the width property is not inherited by the "trow" class, despite me explicitly putting in a "width: 100%;" property in the style sheet. In FireFox, there's no issue, so if you want to see ultimately what I'm going for, it's there. It's just in IE for some reason.

I'm not sure what specifically is causing this, and I was wondering if anyone out there would be able to take a stab at it.

(Note: I've removed all the other code for this page since the problem is isolated to this specific area.)

Thanks.

Note to mods: can we close the thread? I figured this out. Like an idiot, I had the solution from another website staring me in the face the whole time and didn't realize it. Go me.
