CogVM

Thanks Levente,

Now, I continue to try Cog, and I have different bugs:
- graphical bug: someties, when I move a window, text disappears during the move. (I put a screenshot in attachement)

- Metacello/Monticello bug: I cannot reproduce it easily. When I load my metacello Script (ConfigurationOfO2 and ConfigurationOfMoose for example), sometimes the VM crash.

For information, I use the latest Pharo core (12011) with the cog changes integrated.




Cheers,
Jannik
