Being visible to some users in "hidden mode"

[Max Paint]

This is a "bug" I had since IM1.4.0. As far as I know, this mod worked in IM1.3.2.

Do you remember the small icons in friends list? I mean these [flash=,:1p8rxis5]http://www.maxpaint.de/templates/BBLite/images/icon_not_visible.gif[/flash:1p8rxis5] . As far as I remember you were able to change these pics by simple click. Checking it meant that some users were able to see your onlinestatus although you're surfing in hidden mode.
But the fields list does not appear anymore. I think it is allow_view_online. You can change these settings via phpmyadmin and then you get the other picture.
