Every time I sign in it takes very long (like 5 minutes) until my contactlist actually appears, before that, the whole 5 minutes, the msn-window is empty and doesn't react, until my list appears. Then there are already windows blinking of people who have already spoken to me in that time. Then I only have a couple contacts online, en again after some time, the rest signs in (a whole load at a time). My pc is new from september so that won't be the problem. I enabled de UPNP port on my router, and the other pc connected to is has the same problem. People I know have the same problem, and do not have a router. When we all try 5.0 it's solved. What's causing this problem?
