2 layout problems FF + IE when resizing browserwindow

[tilto]

Hi,
i have my site looking like this :

http://pastie.caboo.se/private/ugbweejni3vzwjiizjatxw

with layout.css like this :

Code: Select all

#menue {width: 96px; float: left;}
#hintergrund {float:center;}
#topquer{
background-color:#bf040d;
color: #FFFFFF;
padding:0;
margin:0;
height:80px;}
#inhalt{
width:700px;
border-top:0px solid #E4E4E4;
margin:0px;
margin-left:auto;
margin-right:auto;
padding:0px;}

#topkurz{
background-color:#000000;
color:#9B9B9B;
padding:0px;
margin:0px;
height:20px;}

When i open the page in Firefox everything is allright except that when i resize the browserwindow at some point the 2 div sections hit the menu on the left. this would be no problem if there were just pictures, but because i have labeled the pictures the text-links get a red backgroundcolor.
My second problem is that IE begins drawing the sections under the menu for some sick reason when i resize the window. i would really like to know how i can avoid those events without forcing my website to load in a prescaled (unresizeable) window.
sorry for my bad english & thanks in advance!
