I've used PHP Version 4.0b4pl1 and it worked OK (except few bugs). Now I'm trying to use final release (win32 binaries downloaded from www.php.net) on Windows 2000 Advanced Server machine, but there is a problem. I set session.auto_start = 1 in php.ini file and page crashed (the same problem is with session.auto_start=0 and session_start(); placed in xxx.php file). When I set session.auto_start=0 everything's OK (but I need session variables). Here is php.ini:

Session]
session.save_handler      = files   ; handler used to store/retrieve data
session.save_path         = c:\app\php4\tmp    ; argument passed to save_handler
                                    ; in the case of files, this is the
                                    ; path where data files are stored
session.use_cookies       = 1       ; whether to use cookies
session.name              = PHPSESSID  
                                    ; name of the session
                                    ; is used as cookie name
session.auto_start        = 1       ; initialize session on request startup
session.cookie_lifetime   = 0       ; lifetime in seconds of cookie
                                    ; or if 0, until browser is restarted
session.cookie_path       = /       ; the path the cookie is valid for
session.cookie_domain     =         ; the domain the cookie is valid for
session.serialize_handler = php     ; handler used to serialize data
                                    ; php is the standard serializer of PHP
session.gc_probability    = 1       ; procentual probability that the 
                                    ; 'garbage collection' process is started
                                    ; on every session initialization
session.gc_maxlifetime    = 1440    ; after this number of seconds, stored
                                    ; data will be seen as 'garbage' and
                                    ; cleaned up by the gc process
session.referer_check     =         ; check HTTP Referer to invalidate 
                                    ; externally stored URLs containing ids
session.entropy_length    = 0       ; how many bytes to read from the file
session.entropy_file      =         ; specified here to create the session id
; session.entropy_length    = 16
; session.entropy_file      = /dev/urandom
session.cache_limiter     = nocache ; set to {nocache,private,public} to
                                    ; determine HTTP caching aspects
session.cache_expire      = 180     ; document expires after n minutes

Can anyone tell me what's wrong ?

Thanx.
