Dear All,

I have been working with ndnSIM and when I run a scenario and I close the visualizer I get this:

marzieh at marzieh-VirtualBox:~/ndnSIM/ns-3$ ./waf --run=ndn-simple --vis
Waf: Entering directory `/home/marzieh/ndnSIM/ns-3/build'
Waf: Leaving directory `/home/marzieh/ndnSIM/ns-3/build'

I was wondering if there is a way to fix this? or is it important to fix?

Best Regards,
