I will try to upgrade and test it soon.
Many thank.

By the way, I wonder whether you have tested it with LaTeX export or not.
The HTML export works perfectly in my case, too, but LaTeX export does not as said.

Regards,
Joseph

Guidance: Upgrade your version of org-mode.

Exporting the following subtree to HTML works for me

,----[ test.org ]
| * Export test for ampersand
| This & that is cool.
| This \amp that.
`----

,----[ test.html ]
| ...
| <h1 class="title">Export test for ampersand</h1>
|
| <p>This &amp; that is cool.
| This &amp; that.
| </p><div id="postamble">
| <p class="author"> Author: Bernt Hansen
| </p>
| ...

My version of org-mode is Org-mode version 7.4
(release_7.4.89.g4ed00.dirty)
