Error is not in session cookie. Session cookie error happens because
script outputs warning about file open failure.

open(C:\PHP\sessiondata\sess_e6134f15c778dc92b4ca18c070690a2b, O_RDWR)
failed: Permission denied

Issue is specific to some restriction on win2k3 or session file locking
problems. I think issue is not related to SquirrelMail. Any PHP session is
affected. It might be SquirrelMail issue only if you use some third party
plugins that corrupt session information.

When does it happen? Does it happen after some cleanup in
c:\php\sessiondata? Or after session timeouts in 24 minutes?

Please don't confuse 1.4.6 and 1.4.6rc1 versions. 1.4.6 version is not
released yet.
