I would be extremely grateful if you could cast your eye over the following problem and give me some advice if possible.

I have a WEB site index.html page (www.woodmereassociates.com) that uses the following code to read and
display a normal text file. (I found this code on the WEB)
It works as advertised, quite well, with all of the browsers (Foxfire,
Apple's, etc.) I've tested except with MS IE8 & IE9 and maybe earlier versions as well.

When I access the WEB page by entering the URL in the address line, I see the context of the text file as desired.
However if I navigate to any other page on the WEB site and then return to the Home Page (index.html),
the text file content is not shown.

My bypass is to use the text "id="dsp">Check with
one of our agents for Our Featured Listing particulars." text is used within the html code. (see code near the end).

Thinking that this might be a cache problem, I've tried several methods to make the browser not reuse cache, but to no
avail. ie <META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">

Any ideas?

If need be I can post the entire page.

Thanks, Bob Miers

Seems to work in my IE emulator (all IE versions) when I put the p#dsp element before the script instead of after (you might also wrap the whole script in an onload event).

BTW it seems Chrome/Iron's and Opera's default settings don't allow offline AJAX file inclusion, their error consoles saying "Cross origin requests are only supported for HTTP" and "XMLHttpRequest to files is disabled for security reasons", respectively.
