I think the problem is that the:
Code:
<div class="dropmenudiv" id="dropmenu2"
and similar have no background. Considering your markup and its appearance, an all but transparent .png image would be good for this, however, without some kind of 'pngfix' and even with it, this may not be suitable for IE 6. A fully transparent .gif might work, though it might not.
Iframes may be made transparent in IE, though this might give rise to the same issues. But if that works out, the code for the iframe could be made specific to IE or to just those versions of it that require it.
