It returns false intermittently in the web app with no observably changed
variables.  The number of browsers open seems to have an effect, but it is
not identifiable as a fixed set of conditions.  I logged on once, and it was
working.  Within the same session, it suddenly stopped working.  Then I
opened a new session, and it didn't work at all.  Then, I opened a debug
session on IIS from VS, and it worked.  Then I opened a new browser session,
and that worked, and then starting another debugging session in VS gave the
error.  I changed nothing except opening and closing sessions.
