Thank you. Now it´s working great.
I have another problem.
I disable IM window on startup (option Display_IM_onStartup=0), but it´s working only for user that are members of groups (I´m using SPECIAL_MODE_GROUP_COMMUNITY). When a users that are not member of a group runs IM, the window is shown.
Can you fix that or show me what I have to do?
Thanks in advance.
