Publishing to website causes FrontPage to generate duplicate html source for webbots

I just started having a frustrating problem today and am unable to determine
its source. I have a page laid out using a table to define the different
page areas. In the topmost row I have a webbot include that includes another
HTML file containing the banner source. I also have one for the navigation
menu that appears in the leftmost cell of the middle row. When I view my
page in FrontPage using the Normal view or the Preview view it appears
correctly. When I select Preview in Browser from the File menu it appears
correctly. When I publish to the website on my machine it is generating
incorrect code for the webbots. The simplest explanation is that it is in
some fashion duplicating the inclusion code, but also portions of the table
code. The effect is that I have two of everything and they are somehow
interwoven. In other words, it isn't simply one copy of the entire table
followed by another copy of the entire table. It is somehow getting confused
and generating incorrect code. I am surmising this because the Preview in
Browser worked fine.
