I just installed HORDE RELENG_2 and IMP RELENG_3 and when I go to the compose screen I see the following at the very top of the page. I have PHP 4.2.2 installed on the system and I can't figure out what is causing this error message, any ideas? Notice: Undefined index: attachments_file in /usr/local/apache/htdocs/horde/imp/compose.php on line 1046
