amaya 9.4 on xp transforms my code ... but i don't want it !!!

Hello,
i'm french, so sorry for my english, i'am newbie with amaya so sorry for
"candide" questions.
I opened a existing document, in fact with a php extension but a html doc,
with two lines of php script.

Amaya, on first line replaced my "href="<?php ..."  tag by a "href="&lt;?php
..." and the second line "<?php
include($_SERVER["DOCUMENT_ROOT"].'/briquesainclure/pagesweb/menu_00.php');
?>" was just deleted !!!!

Are these bugs? Is there any knwown way to keep my code line and my "<"
