  We illustrate some of the preliminary results obtained with a new sample of
flares and a new analysis. In these proceedings we deal mainly with the
analysis related to the flare energy and describe the work in progress to
measure the average flare luminosity curve. We discuss in brief GRB050904 and
GRB050724 for matters relevant to this work. In particular we measure the
contribution given to the flares by GRB050904 and give a new interpretation for
the decaying early XRT light curve of GRB050724. We briefly illustrate the
first evidence that the early decay is given by the subsequent emission of
events with Width/TPeak < 1 and the total energy of these events is larger than
the energy emitted during the prompt emission spike showing, indeed, that not
only the central engine may still be active after hundreds of seconds of the
first spike but that this may still be part of the prompt emission.
