1) Script Title: IFrame SSI script II

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/iframessi2.htm

3) Describe problem:

I am having a problem with a dynamic iframe resizing script I got from Dynamic Drive. The script works great in all browsers but Safari and the issue is this:

When the first page of content loads into the iframe it resizes the iframe height properly. However, when you click a link on the page that has loaded into the dynamically generated iframe, it does not do an automatic refresh of the page in Safari so the content of the second page loaded loads at the top of the iframe. The problem is, if the first page loaded is longer than the second, the user sees nothing because the content is at the top of the page and the page has not refreshed and therefore not resized the iframe according to the new content. This only happens in Safari.

Here's an example page I am building with the problem https://www.sweetgrassfibers.com/womtop_test.php

Can anyone help?

Doctype, script and iframe code all below.

Thanks!
