Comment #6 on issue 334 by cy.delau...(a)gmail.com: While computing duplication SmallDude does not show a progress bar http://code.google.com/p/moose-technology/issues/detail?id=334 I just pushed some code in smallDude repository, to display a progress bar when computing. You should have a #computeDuplicationDisplayingProgress in MooseAbstractGoup. It could be used in replacement of #computeDuplication. The problem is that it does not interact well with the moosePanel when this one is open (the panes of the moosePanel start to flicker a lot)
