I pasted the following at the bottom of your example:

 

 

Now, if you click Submit, nothing changes.  however, if you look down at the XHTML code, you get:

 

  <div>
    <font class="cap">
      <strong style="font-size: 12pt; color: #000080">T</strong>
    </font>he <font class="booktitle"><strong>Spiritual Life Development</strong></font> course </div>

 

With a little cursoring around, you will see the space after the T</strong> above.  This is the problem.  Since you are not redisplaying the XHTML output, you don't see it, but if you save the XHTML output, and then later reload it into the editor, the space will then display.

 

Note that I submitted a report earlier about extra spaces being inserted in the XHTML output.  Same problem.  As I recall, you never responded to the previous issue.

 

Thanks,
