Cookie Problem…. losing my mind…..

Alright, this doesn’t make any sense to me at all, but I have to ask….

I’m placing cookies to keep track of a user’s login name, and it is working for all of my customers except for 2 in Europe. Both are using IE 5.5, and both have all the settings correct to accept cookies…

There isn’t some kind of special workaround that I have to use to set cookies in Europe is there? I’ve never heard of that, but it’s the only thing I can think of….

Any sort of advice at all would be appreciated…
