We installed the PHPOpen Chat in both systems to make a benchmark to my newspaper.

Linux ok - Localization to Portuguese-Brazil ok - Flag ok >>> worked 98% well. Will need some customization: Logo and new CSS.

Windows 2000-IIS 5 or Apache 2-PHP4-MySQL3 >>> don't worked.
The logon page ok,
The Chat window: didn't view the chatter's list and didn't show the welcome message to the chat room
and if we closed the POC chat window appears the error: Fatal error: Call to a member function on a non-object in c:\inetpub\wwwroot\poc\input.php on line 76.
We appreciate your help to conclude our tests.
Later when we publish the article we will send you the URL about the PHPOpenChat.

If you like to use our Brazilian files, we will send to you. Are our contribution to product.

Thanks
Pierre
