HTTP 500 error when re-opening a message

[Julien@TLD]

Hi,

I have recently installed RoundCube 0.2.2 on my Windows Server 2003 machine with IIS 6.0 + PHP 5.2.9 TS + FastCGI Handler 1.0 + MySQL 5.0 + hMailServer 5.1.2 as IMAP and SMTP server.

In fact, I can login, send messages and read messages but when I click on an unread message (in bold), the message open well and I can read it and then if I return on the main page and if I click yet on this same message (already read this time), I obtain this HTTP 500 error in the browser (IE8 & FF 3.5):

FastCGI Error
The FastCGI Handler was unable to process the request.
--------------------------------------------------------------------------------

Error Details:

•Error Number: 13 (0x8007000d).
•Error Description: Données non valides.
HTTP Error 500 - Server Error.
Internet Information Services (IIS)

This is the only error I have with RoundCube. Everything else runs fine. I have opened the PHP and RoundCube log files but nothing is related to this error.

Do you know why I have this strange error ? I don't see why I can open a message one time and why exactly the same action cause an error 2 seconds after...

Thanks.
