I included only system/libraries/session.php only.It's working fine in some systems IE7 browser..
I want to change any options in my browser?

[eluser]TheFuzzy0ne[/eluser]
Why are you editing the core files directly? You should be extending the core files in ./system/application/libraries/MY_Session.php.

Check the permissions for c:/wamp/tmp, and ensure that "everyone" can write to it.

- Permissions is the first port of call as the guys have said
- Then make sure that your 'cookie_domain' in your config.php is reflective of your 'base_url' - if these differ you will get probs
- Make sure you dont have underscores (' _ ') in your domain e.g. for your test server or something.

It sounds like your cookie are still not configured correctly. Either that, or you might be adding too much data to the cookie somewhere, and it's breaking.
