drupal messages not showing because of unsettins session variable

Hello, I believe that line 11 in phpfreechat.module causes all drupal messages such as user profile change confirmation etc, to be lost.

The line is unset($_SESSION['messages']) which destroys the session messages variable. After commenting it out, drupal messages get displayed correctly.

Upgrade: Apologies, I now see this is a duplicate issue same as http://drupal.org/node/548928
