Detect Current URL Of PDF File In Different Frame Not Working In IE?

The system uses individual PDF files for each page, and you can navigate using the controls on the side. It's not ideal, as it was made to replace a horrible system and has the limitations of the content being presented.

That being said, I think it's pretty good. The trouble area is related to navigation: when you navigate the documents, some JavaScript detects the current URL of the content frame and updates the nav controls (previous and next page numbers) and table of contents links (bold, highlight) if they have changed. That part works fine. The problem area is with IE and PDF links. If you click a page link within the PDF, it opens that PDF file in the same frame. In FF and every other browser, the JS URL detection works fine.

In IE, of course, it doesn't detect that a different PDF is being displayed. If it can't detect the new PDF file, and by extension, the file number, the nav controls don't work right. Now - before anyone asks - it DOES work in IE if you navigate to the PDF document by using the links in the navigation system that I built. It's just when you arrive at a PDF from another PDF that it fails.

This is hard to explain more clearly, so take a look: [URL]

To see this in action, visit page 4, the table of contents. Click a page number link, for instance, page 9. Once it loads, click "next page" at the top left of the interface. In FF, it goes to page 10. In IE, it goes to page 5, since the JavaScript is unaware that the frame has changed PDF files. It doesn't make sense, since FF can see it plainly.

My code is all out in the open. This thing has to be designed to run off of a CD as well as on the website. If I could use server-side scripting, it would be VERY different, I assure you.
