That's strange, I'm using version 2.0.14 and get no disconnections anymore; I managed to register a new sim, too (previously used on S40 device).

Anyway I cannot create groups, nor manage groups I previously created..

To clarify the problem, log referring to following actions is attached:

1) I create a group adding a single contact
2) my yappary reports that group is created successfully (other contact does not get notification)
3) I try to leave group, window closes itself, anyway group is still there in chats list
