I have a strange problem with friechat.
in the user list USER who is already login can see new users who login after him
but the new user who just login can't see the old user.
to make sure that the user is realy online and not apearing in friechat i published the module CB Online, that show all the register users that are currently online.
i chacked in the chrom tools and didn't find any error related friechat.

i'm using joomla 1.7 Cb 1.7 friechat 6.2.2

my website at http://wannabiz.biz
i will sent you 2 test users with contact us.

I checked and it is working perfectly,
and one more thing, try installing the latest version (6.3.1 currently)
it has RTL support by default.

i see right now tht you are online with test and xxx
i'm online also as kloper
in my user list for the chat i can see only xxx not test and not yael

It seems more of a browser problem to me.
Try it from a different browser.
