    Ok, I will try.

    Maybe the model but I maybe did something stupid: I opened the models
    with the M3 modeler then saved them. Still the crash. Then reverted to
    M2 (without changing the models). Again a crash.... which seems to
    tell us it is not M3.

    But: are the model formats compatible between M2 and M3 ? In other
    words, can I continue to work with M3 modeler whatever version M2 or
    M3 of Cayenne I am using?

    Thanks,

    Alex
