[CSS Issue]Navigation menu rendering on IE incorrect when browser resize.

Please see below for the issue that I encountered on existing web site that I'm currently working.

Expected: Graphics and text will be resized proportionally to the new browser windows size.

Actual: Text in the button creates a new line of text, thus overlapping the other ones, and when you hover to the drop down button (My Time), it disappears when hovering to a portion/ text that has been overlapped.

Here's the CSS that it's currently using

#menu {
    ;
    height:91px;
    background:url(images/menu.png) repeat-x 0 center;
