Several times the NIS Edit has become not responding. Once after compiling and running a script. Now while just viewing a script (no operations performed other than to scroll up and down). I am using nisedit2.0.3.exe that I downloaded today. Windows 10 version 1511.
Thanks, Jim (fjrohlf at gmail.com)
