Hi Javier, I'm afraid this change will fix your app only to break others (including existing OSG manipulators/callbacks) that assume that the event time is based on the ReferenceTime.
Perhaps what is required is to add the current FrameStamp to the EventQueue and have events record the last assigned FrameNumber, ReferenceTime and SimulationTime, then allow callbacks/event handlers to pick which quantity is relevant to them, without making assumptions about what the time value is.
