Hi,
I'm using last Moose build on top of CogVM 2550 and each time I click on a method an error pops up (see the attachment). The same problem I have it with older builds of Moose but I don't have any problem if I open the same image with Cog VM 2540 or CogVM from the Pharo web site.

I'm on Mac os 10.7.4 and the image is:

Pharo1.4
