A sublevel under the packages. E.g. package: Blah-Core Tags Blah-Core-Part Blah-Core-Stuff But only one Monticello package: Blah-Core.mcz Tags have no icon and Part and Stuff are shown under the package when you open the tree.

I also tested it on Windows 7 and it works just great. Just a question: is there a way to communicate with an already running VM that was started independently from Pharo?

Re: [Pharo-users] Spec website: nice!

by Juan Ignacio Vaccarezza

Hi Im reading and following the documentation of spec from the new site, And the second example goes: ListModel new items: Smalltalk classes openWithSpec. And that does not work. Instead of that I did: (ListModel new items: Smalltalk allClasses ) openWithSpec. And worked perfectly. I hope it helps improving the documentation. Regards, and thanks for the good work. Juan.
