Issues with Apple login causing problems with Apple sites
Have Snow Leopard.
There is an issue with this site losing the login status if you go to an apple support article from this site - when you come back this area says you are logged in but you can't post because you are logged out - and you can't get back to the log in screen.
Same problem if you open itunes while on this site, close it & you can't post because once again logged out vs logged in.
Only way I found around it is to quit safari, shut down, come back later after apple site as calmed down.
