Hi, From time to time I see a bug in GLMTreeMorphNodeModel>>pathIn:
It happens like this: 1) PPSmalltalkGrammar new inspect. 2) Click to the tree view and do some clicking here and there, expanding and collapsing nodes. 3) After some time, pharo freezes in a enldess recursion call. You can see it in the attached screenshot.
This behaviour is there for quite a time (at least half a year, as far as I remeber).
Cheers, Jan
PS: Where shall I report bugs like this? GoogleCode or FogBugz?
