I have asked this question I Norwegian, but since no one has come up with an answer, I'll try it in English.

Many years ago I made two groups for members of a club I am working for. Now, after I updated my Windows Live 2011 to 2012, these groups have started to act "funny". Egg: One of the groups has 45 members, called member contacts.. It is there, as it should, in the listings over groups. And, when I enter the name of the group, in the addressee's field, it is there in bold characters. BUT! Before it had a +-sign in front, and when I clicked on that, all the member came up. Now there' no +-sign, and no one occurs, and when I try to send it I get the message that I need to enter addressees! What has happened? What can I do to get this rectified? It's a nuisance!
