Silent Sorrow: The OnMouseOver scripting that I know is this:

-----
<a href="Your Link Here" onmouseout="self.status='';" onmouseover="window.status='Text here that you want to appear in the status bar instead of the link address';return true">Your Link Here</a>

I hope that was what you were looking for. And for the transparent Iframes. What do you mean by that?
