Shoutbox distorts page view on alternate posts

Hi,

I am facing a problem with the shoutbox module for Drupal 5.1 installation.

When I post my first message, it's all well. But, when I post my second message, the page reloads and the page appears inside the shoutbox, distorting the page view. When I press refresh, it becomes normal again.

This happens, only when it displays the message "Your shout has been submitted". It doesn't display this with every post.

I have attached a couple of screenshots. Please help in resolving this.

Thanks and Regards..
