Two specific issues in conflict:
The Events Calendar conflicts with Tribulant’s Newsletter plugin. The month pulldown at the top of the calendar page shows incorrect months and does not update correctly when switching back and forth between months.
Newsletter plugin also makes any event on the last day of a month display every day on the following month. For example, Halloween, occurring on October 31, will also display for every day in November.

I have not found a hack or solution in forums here or at Tribulant. I have also posted a support ticket with Tribulant.
Thanks for any assistance.
