help me find out what nav script the website used!!

[Aris]

I like the drop down menu on http://www.clsmartsourcing.com/.
I checked the source and found this script:
<script type="text/javascript" language="JavaScript1.2" src="stm31.js"></script>
and some code:

stm_bm(["bmgmfhr",430,"","blank.gif",0,"","",2,0,19,19,200,1,0,0,"","600",83886139],this);
stm_bp("p0",[0,4,0,0,4,2,9,7,100,"progid:DXImageTransform.Microsoft.Pixelate
Is it a free script? Does anyone can enlight me?

Is there anyone familar with this?

If it doesn't have a copywrite on it, it is free... but be sure you give credit to the person who created it... you might want to validate this with the site first
