Problems with inserting html code in FCKEditor

Hi,

I have a mail system with fckeditor to edit messages (write, reply and forward).

The problem is when I will reply or forward an email message. I get the content of the email and put it in the value propertie thats represents the text box of FCKEditor, like it: <input type="hidden" id="body" name="body" value=" &lt;br&gt;&lt;br&gt;&lt;br&gt;[] Guilherme Zanetta Simoni&lt;br /&gt;"

I'm using htmlentities function from PHP to put it on the text box. The problem begins when it shows. The content appears to be normal, but when I click in the 'Source Code' button, the hole code of the email i was trying to forward/reply disappears, so when I go send e email...has no content.

I'm using version 2.4.3

Anyone has any idea?

Thanks.
