Version: (using KDE 4.4.2) Installed from: Unspecified Linux When moving a recurring event to a different hour, previous versions of the software would ask if the user wants to move all events, only this event, or this item and future events. However, in KDE SC 4.4.2 using the iCalendar resource the software moves this and all future events without asking. Furthermore, it _deletes_ all previous events! This is a dataloss bug.
I haven't seen this in a long time. Please try with kdepim 4.6.
