Hi, With the recent changes in Mondrian it looks like the class blueprint is broken. The problem seems to be due to incorrect bounds of the parent node. I noticed when by spawning the blueprint of a hierarchy of classes, I got overlapping classes. I will take a closer look, but it would be great if someone could confirm this problem. I guess it should happen with other nested visualizations. Cheers, Doru -- www.tudorgirba.com "Reasonable is what we are accustomed with."
