yesterday, when looking at the "who's online" page on my site, as admin I can see who is invisible, their name show sup with (I) next to it, and I could see myself int he list as well, today, I'm not seeing anyone like that, and I am not showing up in the list either.
now, it may be no other invisible users are on, but I would at least expect to see myself in the list as usual.....
