Problem

I need the content to force to scroll on X axis, not down the Y axis.
HTML
I know this is formatted badly but it's dynamically generated and has no white space.
<div class="folderWrapper" id="folderContainer"><div class="folderBox ui-droppable folderBoxSel" onclick="folderSelected(0)" id="fBox0"><div class="counter" id="fCount0">4</div><div class="folderName">Unsorted</div></div><div class="folderBox ui-droppable" onclick="folderSelected(1)" id="fBox1"><div class="counter" id="fCount1">0</div><div class="folderName">test</div></div><div class="folderBox" onclick="folderSelected(1)" id="fBox1"><div class="counter" id="fCount1">0</div><div class="folderName">test</div></div><div class="folderBox" onclick="folderSelected(1)" id="fBox1"><div class="counter" id="fCount1">0</div><div class="folderName">test</div></div><div class="folderBox" onclick="folderSelected(1)" id="fBox1"><div class="counter" id="fCount1">0</div><div class="folderName">test</div></div><div class="folderBox" onclick="folderSelected(1)" id="fBox1"><div class="counter" id="fCount1">0</div><div class="folderName">test</div></div></div>
Formatted nicely with one folder inner box:
<div class="folderWrapper" id="folderContainer">
<div class="folderBox ui-droppable folderBoxSel" onclick="folderSelected(0)" id="fBox0">
<div class="counter" id="fCount0">4</div>
<div class="folderName">Unsorted</div>
</div>
</div>
CSS
.folderWrapper{
overflow-x:scroll;
overflow-y:hidden;
height:85px;
white-space:nowrap;
margin-bottom:5px;
}
.folderBox{
float:left;
background-image:url(../images/artworking/folder.png);
background-position:center top;
background-repeat:no-repeat;
width:85px;
height:55px;
position:relative;
padding:5px;
z-index:4;
white-space:nowrap;
}
.folderBox:hover{
cursor: pointer;
}
Thanks if anyone can help!
Edit
Bazzz's answer works in all browsers except IE compatability mode (unfortunatly it has to be compatible) which gives the following look:

With IE hack:
