i've noticed that the selection of the analysis method is currently made with a check box so a multiple selection can be activated at the same time (anyway, i haven't tried what happens by starting calculation this way).
to activate a different method, the user has first to deactivate "bishop".
maybe, the selection of the analysis method could work better with a radio button.
also, every time hyrcan starts with the bishop method as default. i think that could be better that the program started with the last method used.
