Close Button not visible in IE but is in FF

[knelson]

1) Script Title:

2) Script URL (on DD): dhtmlwindow.js and modal.js

3) Describe problem:

I'm opening a modal window using:
var loginwin=dhtmlmodal.open("loginbox", "iframe", loginurl, "Login Required", "width=580px,height=400px,resize=1,scrolling=1,center=1", "recal")

The Close Image button (top right corner) is showing in FireFox 2.x but is not showing in IE 6. The button is on the iframe page because I can hover over it with my mouse and it displays "Close". If I then right-mouse over the top of where the close button is supposed to be and click "Show Picture", the button shows.

After that, I can run the code to reopen the window and it works fine every time. Once I close IE and start over, the image is not visible until I "Show Picture".

Can someone point me in the right direction on this?

Thanks!
