What do you mean when you say 'use of the back button'? Do you login, then click back or just click back when viewing threads? Because I use the back button and haven't had any login problems.

Give Opera a go - it clearly is the superior browser!!

EDIT: I just assumed you were using IE, but if you are using Opera, then I dunno what the problem could be apart from cookies - you do have them enabled?

Also wanted to add for those who didn't know, with Opera, you can block pop-ups, the ads on AO don't appear (for some reason...but I ain't complaining) and it has 'mouse gestures' - they are the sensational!!
