Menu bar problem

[liunx]

I have two menu bars on one page, one on the top and another on the bottom. <br />
Every time my window resizes and horizontal scroll bar shows, bottom menu bar moves up for scroll bar width. After that I have to refresh window (IE) to mmove bottom menu bar down. What shall I do?<br />
<br />
#menu1 { <br />
background-color: #000000; <br />
border-style: solid; <br />
border-width: 2px; <br />
border-top-color: #f0f0f0; <br />
border-left-width: 0px; <br />
border-bottom-color: #ffffff; <br />
border-right-width: 0px; <br />
