hmm...yes, the window opened notifier was a good feature
As far as I understood, the problem is that msn messenger 7 retrieves the dp when they open your contact card, or in the final version, have the little dp in contactlist preview thingie enabled...
I think you could try to add it again, but then add a clear note that they may just be retrieving the dp and that it is highly unrelieable, and instead of saying that "the contact has opened a conversation window with you", change it to, "the contact
may have opened a conversation window with you" or something like that. The name could be modified from "window opened notifier" to...[insert good name here].
Bah..I guess that's too much work and it's just too unrelieable....
