After a few students started having the session switching issue, which is really due to misconfigured webcach at the students ISP, I decided to double check our blackboard patch level, etc.
Turns out the blackboard app reported we were quite a bit behind. 6.2.3-6 We should be at 6.2.3-23
Darn! I could have sworn I did that upgrade at the end of summer.
Darn! Its even listed on my board and checked off.
Darn! Its even listed in this blog as being done on 8/19...
Wait a minute...
It seems the version number comes from a file that was
replaced with the old version, causing blackboard to display the old version number.
I'm still working on verifying that the SP3 upgrade was done correctly.
