Flash on both sides of the page

First of all merry Christmas everybody and a happy new year.

i am working on a website with 3 coloms

#contleft	{position:relative;float:left;width:150px;height:960px;}
#container	  {position:relative;float:left;width:700px;height:960px;}
#contright	{position:relative;float:left;width:150px;height:960px;}

<div id="contleft"></div>
<div id="container"></div>
<div id="contright"></div>

what i want is to have 2 flash elements 1 on the left side and 1 on the right side of the page. The above code works fine in FF3 but in IE7 the right flash element appears aligned under the left flash element

but when i change #contright in

{position:absolute;float:left;width:150px;height:960px;}

it works perfect in IE7 but in FF3 the right element disappears.

this link show its good in FF3 Good in FF3

and this link shows that its good in IE7 Good in IE7

its XHTML Valid so the problem is not there.

Thanx for your help,
