background gif doesn't fill scrollable IFRAME

problems with IFRAME

[DeWayne]

Greetings...

I'm having problems using IFRAME..

I have a background gif in the body of the code that is to be displayed in the IFRAME. However the background is only the height specified in the window.open. If, in this case, the actual height generated by the HTML is more than 640, scroll bars are generated, I can scroll down to see the rest of the content, but the background gif is missing past 640 pixels...

Is this an HTML or browser restriction? It does the same thing in IE5.5 and Mozilla 1.6....

Any ideas would be much appreciated.

Thanks,
DeWayne

Here are snippets of the code:

function openWindow2 ()
{
satModules = window.open("","satModules","width=780,height=640,left=30,top=50,dependent=yes,scrollbars=yes");
window.satModules.focus();
}

<li>
<a title="[Alt+2] my profile" accesskey="2" onclick="openWindow2()" href="profile.php?PHPSESSID=e6646b93d79146f01ae7e60a7fe08160" target="satModules">
my profile </a>
</li>

BTW, this is XHTML....

I'm a bit confused, here. Is this an iframe or a pop-up window?
