Very nice module overall. I've been having one problem though on duplicate entries. It doesn't happen all the time, but so far, it happens if I make a recurring appointment and then specify the recurrence as:

* By Month, specifying a specific day of the month
* By Month, specifying last weekday of month
* By week, every 2 weeks

It duplicates the event on the first day of the recurring appointment.

However, it didn't do this on:

* By Month, Xth weekday of the month (2nd Sat, 2nd Tue, 4th Wed all worked fine without errors).

Is there a code fix somewhere for this, or should I try to provide one? It doesn't appear to be linked to the "summer time" issue (aka Daylight Savings Time)

Thanks for any help or direction so I can fix this.
