session ?

Hello, I've been working with sessions all day and found some strange behaviors. With 4.1.0 I couldn't register and pass objects, so after a while I upgraded to 4.2.0-dev. Same problem. I wrote a user handler using MySQL and almost solved the problem but here I bumped into another problem : __sleep() and __wakeup() would trash my session data : count, instead of a simple int, turns into $PHPSESSID. If I *add* another class (B) without the __* functions, B works OK but the other one doesn't. The rest of the session vars work normally. RHAAAAAAAAAAAAAAAAAAAAAAAAAA =8\ The testing requires 4.1.0 and 4.2.0_dev + a simple file setting up two classes and count. One of the class must use __* functions. Also, when I wrote the MySQL session handler I had many problems making it work. Under 4.1.0 it just keeps adding new sessions. Under 4.2.0_dev, it works fine with different files. Reloading the file keeps adding new sessions. Either I do not know how to handle sessions and then I pledge for help, or there is something rotten. hellekin
