Who's Online

Just a quick question. When I check who's online in my Admin panel and I include the spiders, are these actually people checking that page or is it just spiders from the search engine?

If you set it to not exclude spiders then it shows both and you look at the left side of the line and it will tell you if it is a spider or a guest.

i think they are guest ?

When I'm in the who's online admin screen and I change any of the options like view spiders etc... I'm immediately forced to login before seeing the changes. Is there some reason for this and can it be fixed? I'm using v1.5.0. Also only one option can be changed at a time and selecting another option after the re-login process resets all the other options back to their respective defaults.
