Comment 1 for bug 80191

It got fixed some time ago now. Nowadays skins are specified in instance configure.zcml as default browser skin.

It was also fixed in CanDo, see setup.py:
    [schooltool.instance_type]
    cando2007 = cando.cando2007

And in cando/cando2007/configure.zcml:

  <browser:defaultSkin name="NewCanDo" />
