Opera Box Width

Opera is displaying a width which is way too big...

I have a div that is supposed to be auto width. It is positioned left 171px. And fills to the correct width in IE, Firefox, but displays enourmously too wide in Opera.

I don't have much experience developing for Opera, anyone have any ideas?

CSS:

/*-- layout --*/ 
div#Header { 
margin: 0px; 
padding: 0px; 
width: 100%; 
height: 96px; 
text-align: left; 
background: transparent url(../images/tech_bg.jpg) top left no-repeat; 
} 
div#Flowers { 
position: absolute; 
top: 0; 
left: 0; 
width: 154px; 
height: 217px; 
background: transparent url(../images/flowers.png) top left no-repeat; 
z-index: 3; 
} 
div#Flowers_Mid { 
position: absolute; 
top: 0; 
left: 154px; 
width: 51px; 
height: 213px; 
background: transparent url(../images/flowers_mid.png) top left no-repeat; 
z-index: 3; 
} 
div#Flowers_Right { 
position: absolute; 
top: 0; 
left: 205px; 
width: 202px; 
height: 161px; 
background: transparent url(../images/flowers_right.png) top left no-repeat; 
z-index: 3; 
} 
div#Title { 
position: absolute; 
top: 46px; 
right: 16px; 
width: 293px; 
height: 50px; 
text-align: left; 
z-index: 4; 
} 
div#Content_Wrap { 
position: absolute; 
left: 170px; 
margin: 0 16px 16px 0; 
padding: 10px 20px 20px 20px; 
background-color: #FFFFFF; 
border: 1px solid #F2490E; 
}

Can you post the relevant HTML as well? Which div is it that is the problem?
