The lead developer for the original product on which this one was based, had
a strong feeling that employees were taking lunch too early, and that
productivity would be improved if they worked until at least 1 o'clock
before unharnessing and goofing off.
Seriously, it's a bug, one of a number related to date and time
functionality within the beta.
Times between Noon and 12:59 PM don't work.
10:00 AM looks strange in the UI, but works.
Scans scheduled for a specific day of the week happen, but two days
preceding the scheduled day.
If your long and short date format (not sure whether it is either or both)
are set to other than the defaults for your locale (first choice in the
drop-down box)--the beta may expire unexpectedly, or refuse to run on first
installation.
