When the Appointments group has more than one B.O in it, and process is set to force the calendar to ask which B.O you want to create when clicking in an empty time slot (e.g. ENTER NEW Appointments) Then Appointments.StartTime is not populated.
There are two possible bugs.
1) V5.9 did not require to create a process to work. it automatically detected the query was against the group - not an individual B.O within the group and prompted the user to select which B.O you wanted (Appointment, task, Event etc)
2) Querying an individual B.O of the Appointments type - the StartTime IS populated, but when querying a group - it isn't
Finally 3) some erratic behaviour seems to have returned which we got rid of in the V5 run - If a calendar is located in a tab area and a "Home" menu option forces a reload of the Visual Perspective - The calendar gets clobbered and isn't redrawn.
