google translate flag

Hi everybody,

I could manage to add google translator flags inside my menu bar but unfortunately it is looking nice only in chrome.
In ie, the flags are appearing outside the menu bar, not in the same menu line but in a new column at the end of the bar with large buttons associated to the flags.
I appreciate if someone could give me a clue.
The style and html used are this:

<style type="text/css">
 
ul#menu
{
width:auto;
height:30px;
font-size:13px;
font-weight:normal;
font-family:Verdana, Helvetica, sans-serif;
}
 
ul#menu li
{
display:block;
float:left;
