Iframe SSI script II:2nd iframed page resizes in FF but not IE6

[avdistribution]

1) Script Title: Iframe SSI script II

2) Script URL (on DD):http://www.dynamicdrive.com/dynamici...iframessi2.htm

3) Describe problem:
1/My multi page iframed content includes pagination-when "next" is clicked the iframe resizes to accommodate the new content's height in FF. But in IE6, it reverts to the content's declared min height, and scroll bars appear if the content exceeds the min height.

Rough working example here . Comments boxes are the iframed content.

2/Is there a way to include all iframes on a page, without having to specify the id for each one? [I have a lot of iframes!]
