Close last tab & exit - Crashes
When you have set in global settings (tab bar panel) the exit on closing last tab, when you close the last tab, npp crashes.
I have a win10 x64 and don’t know if it’s due to a plugin I have installed or not.
the easiest way to test if it is related to npp or a plugin is to start
npp without plugins by either renaming the plugin folder temporarily or
by using the -noPlugin commandline switch.
