Hi, (DayPilotPro-7.6.3006.0)
It seems to me that if I change the StartTime for a recurring event instance (i.e. creating a modified exception), the conflict detector still uses the old StartTime (from the Rule) when searching for conflicts. I don't see that problem if I change the EndTime.
All other combinations of Normal and Recurring events are working correctly using Conflict Detection as far as I can see. Conflict detection of deleted exceptions is also running as expected.
Is this a known bug? Any workarounds?
