Well, this wasn’t a bug, but to add a new node on a curve, you make Shift+Clic. And to select an object, you make… Shift+Clic. That’s why nodes appear 🙂
Now, a double-clic adds a new node on a curve!
I was extremely careful to test and retest this without clicking, just mucking about with the group-creation. Just now I went back to version 0.8.2 to retest: No clicking, let alone double-clicking, is involved in reproducing this problem.
That same sequence of events no longer causes this distortion, so, aside from all that, I’m happy :geek: to report that this bug (I still view it that way) has been fixed!
