Hi Andrew.
I'm not sure how all this happened. The doc was working fiine up until the last update before I posted to IIS. My beta testers report that it did load correctly then.
For some reason, Word put all explicit paths in with backslashes and everything went south and naturally it all kept working for me.
Not sure what the deal with IE8 is, the backslashes work for me on three machines using IE8 and others using IE8 have reported that the page loads correctly.
But having said all of that, I have now replaced the backslashes with forward slashes. Please tell me it loads correctly !
Needless to say I will be a lot more careful before uploading another document update. I may actually reformat it all with pure HTML and remove MS Words html bloat and other ideosyncracies.
