the placement of the right side bar before and after login in IE6

Before login in IE6 the right sidebar drops to the bottom of the page. I added this

#sidebar-right {
width:19%;
}

to the fix-ie.css. after this change when you are not loged in the side bar drop to the bottom but after the log in it comes back to the right place.
Note: this is not the case in IE7 and FF3.
