I don't have much to write about today, however, I will say that I'm rather annoyed that I can't complete Lab 3B yet.  I'm stuck at the very beginning where you have to create then activate the new scenario.  I created it just fine, but the problem arrises when I try to activate the scenario.  The log tells me something is still in use by another user and I'm not entirely sure what's happening.

Hopefully Professor Haines will know how to remedy the problem.
