Haha, wasted cpu/hours :) From my experience with the grid 10x10 graph, it might settle down if you decrease the edge(spring) length (in tweaks). Otherwise it just can't fit so many vertices if the edges push too far apart. A smarter graph_editor should initialize with edge length inversely proportional to the number of vertices on the screen. > One broad thought.

I made right-click as the first thing that came to mind, once I removed the drag-n-drop capability. What about hitting 'd' (with the canvas in focus of course) erases the selected vertex? -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org To unsubscribe from this group, send email to sage-devel+unsubscribegooglegroups.com or reply to this email with the words "REMOVE ME" as the subject.
