I have fixed my chat window position and settings (what chat goes where) by exiting the game, reverting to default UI (renamed eq2.ini), set all chats and filters, exiting the game, and renaming back the eq2.ini.
Now all chats are where they are expected to be found
There was something wrong in my UI wich is made with a mix of what I found in this forum.
I hope this will help you all
