Mark Gamble at Luton told me a workaround so I cannot claim any credit
for it.
The problem happens as far as we can tell when the users have bookmarked
- or been directed to - the form login page (default second page) rather
than the gateway page (default first page). What this means in real
terms is that you really do need to go first to the page that has logo
plus "Login" button and use that to get to the page with the login form
that asks for username and password.
There is an article in "Behind the Blackboard" that tells how to
customize login by skipping the gateway page, it gives some code to do
this. I have not tried it so don't know if it solves the problem but
making users go through the extra step of does stop the error!
Hope this is of some help.

We are also seeing this on our student network. I had put it down to
hardware upgrades, however one student told me that he started having
the problem at home only after updating his PC. I haven't seen the
problem from my machine, go figure! I'll be interested in seeing any
solution that anyone comes up with.

Can anyone help me out with an answer to this user? We have just moved
from 5.5 Basic (Solaris) to 6.1 Basic (Windows) via the archive -
restore for individual courses.
I cannot find anything on the blackboard website about this although I
have seen it happen to several users here.
"Why do I always get challenge token null when I log into BB for the
first time? Works fine second time, every time. It's not finger
trouble."
