I don't have time right now to stop and isolate this, but a quick
note... I just loaded PetitParser-lr.228 & PetitCSV-tg.7
and World > Tools > PetitParser menu item has disappeared, which I had
used half an hour ago - on Moose 4.7.
Not sure if you'll see the same thing being just a single observation point.
