anothersystem

Hi this is m y first post, so I'm not sure if it's in the right place. But I have a problem. I am building a system that allows users to sign in, and go through the site, using it's features such as mail, chat etc..., but for some reason, on I.E. 6 some users cannot use their feature instead they are logged out, and always being asked to sign in. The code looks like this &session=%%session%% , on a working machine when the link that contains this script is moused over the status reads session=JDIJLNFIDOI2W3JI(user's session id) but when not working it shows as (session=session) Is there any fix for this, perhaps something that can get arounf I.E. 6. Thanks
