Cookies issue in IE7

[manight]

I've seen many threads on this issue. Did you come up with any possible solution? It seems that upon login on default installs of IE7 the login fails because "Your browsers doesn't accept cookies".
Of course is not true since I log on several sites handling cookies, maybe has to do with how cookies are created, but I think it's an important issue to fix.
Thanks in advance for your kind replies.
