I've been experiencing a crash when deleting a calendar event (right click in calendar, select delete from the popup). Usually I can delete one event without trouble, but the second event I try to delete always crashes.

I traced it to xtpCalendarControl.cpp on about line 2097 in version 10.42 in

BOOL CXTPCalendarControl::DoDeleteEvent(CXTPCalendarViewEvent* pViewEvent)

 where it calls OnBeforeEditOperationNotify (as shown)

    if (!::IsEventExists(pData, pEvent))
    {
        return TRUE;
    }

    //------------------------------------------------------------------------
    BOOL bHandled = FALSE;

    if (m_pActiveView)
    {
        bHandled = m_pActiveView->OnBeforeEditOperationNotify(xtpCalendarEO_DeleteEvent, pViewEvent);
    }

    if (bHandled)
    {
        return TRUE;
    }

The reason it crashes is that pEvent gets clobbered.. (feefee etc)

pEvent is fine before the function, then trash afterwards. To verify, I commented out the OnBeforeEditOperationNotify and it works fine. 

I tried duplicating using the Codejock samples but was unable to do so. I'm using a CXTPCalendarCustomDataProvider with SQL. The project is unicode, statically linked. The problem occurs in both release and debug.

Any hints on what may be going on would be appreciated.

Thank you
