Chattabs locking when making/joining a group

[Shumanjo]

Hoi

Recently I have gotten a problem that starts to annoy me.

Whenever I join a group or make a group some of the chattabs are locking,
as in I cannot change to them or change options for them.

Ie. When I join a group the chat/tell/ooc windows are locked totally, if I am in
"chat" I cannot whatever I do move to "tells", I can see I have received tells,
but the tab is not accessable, and I cannot change other setting than lock/unlock.

If I rightclick I do not get the usual optionsmenu.

I have not changed anything at all in the default setup
