I don't see any approval messages on live.com.
ebuddy.com worked fine and showed me something like 150 approval windows. It really were people that I blocked in the past.
For some reason, ebuddy won't connect anymore. It just gets stuck with the message of "Signing in to MSN as xxx@gmail.com ".
When I tried to log in via mIRC, I saw that all these 1800 users are IN my contact list:

Seriously now, I think something wrong with my very account. It has nothing to do with the specific outdated version that I use.
