Okay, the problem has finally been fixed.
It turns out that Word was leaving in an open quote tag in the post... even though it was not visible when I pasted in my text in that final attempt to get that post to work right.
I was also told this was more of a problem for Internet Explorer users than it was for Firefox users... or the problem would have been solved sooner. The tech was using Firefox so didn't see the problem the first time he looked at it.
I just wish that I had deeper level access to the board code... I could have easily fixed this myself in a much timelier fashion.
