Hi Andrew,
you find the problem. In fact I use almost only MacOS 10,
and two SqueakVM: a CarbonSqueakVM = 'Squeak 3.0Alpha11MT', and a
CocoaSqueakVM from Marcel Weiher. The problem is linked to the
CocoaSqueakVM, I will try to reload a new copy to see if the problem
persist.
Thank you very much for your Help.
