Disappearing <iframe> in IE

[Osiris]

Alright, me with a problem in IE again... *grumbles something about a standards non-compliant piece of ***** This time, it's an HTML/CSS/frames problem. In my web app, I'm using iframes to show different things all at once to both minimize bandwidth usage and to keep the user as up-to-date as possible. My layout looks something like this:

+----------------------------+
|       Toolbar Frame        |
+----------------------------+
|                            |
|                            |
|      Content Frame         |
|                            |
|                            |
+----------------------------+
|                   |  User  |
|     Chat View     |  List  |
+-------------------|        |
|     "Say" Frame   |  Frame |
+----------------------------+

Well, it all shows up just fine in FF, of course, but in IE, the user list frame just... Disappears. Here's a link to an HTML example:

As you'll see, the frame shows up just fine in Firefox, but once you switch over to IE, it's just... Gone.

Help, please?

Its there but IE is having a problem with the percentage height. Add this in between your head tags.

<style type="text/css">
html, body {
margin:0;
padding:0;
height:100%;
}
</style>

The iframe now shows up but makes it huge, but now you have something to work with.

In the head tags of which document, though? Keep in mind that the page holds several documents at once. :P

Ok. I tried, and while it worked for the example, it didn't when I tried to put it in the actual site, it didn't work at all. =( Any other ideas?

In the head tags for the main document not the iframe pages. Personally I think you are abusing iframes, you might as well use a frameset.

I can't use a frameset, because I'd just have to put the frameset in an iframe... As you'll see here in a second. I have another example with the design set in:

Seeing that, now do you get what I mean?

Still in need of some help... I can't seem to figure out at all how to fix it. Nothing I've tried has done any good whatsoever. There's got to be someone who can help me out here... Please? I'll give you a cookie. =P
