first of all thanks to the developers of Z88Aurora for making this remarkable software available for free to everybody.
I have recently started going through the examples of use, and have encountered these two problems (possibly related?):
1. It is very difficult to pick nodes with the mouse/touchpad: they do not get selected easily, even if I enlarge their marks and play with the "angle" option as suggested in the examples
2. trying to solve the above problem, I zoom into the mesh, and Z88Aurora crashes with the message on the command line "./aurorastart: line 8: 5821 Segmentation fault z88aurora"
I am on a debian-8 linux laptop with GPU disabled, and a 2.5GHz i3 CPU.
"Danke" in advance for your help
