Form's select not displaying right

[Roost3r]

Hi,
If you look at my site http://www.xtremehw.com and use the scrollbars then look at my select in my search form you will see that it dissappears or looksweird until a mouse goes over it again; any ideas why this is happening? I want it to work correctly in IE... im using IE6, i tried it in mozilla and it was fine....

After trial and error ive come to the solution that the problem is NOT:
1. CSS related... i removed the css and it still had the problem
2. Related to the american flag image... i also removed that and it still didnt get better
3. Not related to where it is on the page... i moved it above the news and it did the exact same thing...

anyone got ideas?

TIA

heres the forms code
<fieldset>
<legend><b>Search</b></legend>
<form method="post" action="search.php" class="myform">
Search:&nbsp;<input type="text" name="search" id="search" class="mysearch" size="20" maxlength="40" />
<select id="Engine" class="mysearch">
<option value="Google">Google
<option value="Yahoo!">Yahoo!
<option value="MSDN">MSDN
</select>&nbsp;&nbsp;&nbsp;&nbsp;
<input type="submit" value="Go" name="submitsearch" id="submitsearch" />
</form>
</fieldset>

Actually, if we look at your site we don't see anything like the problem you described because you've commented the code out.

I fixed it; but I had to remove the dx filter on the background for it to work right.... weird
