Exiting PS_View

Ordinary exit from the program happens via the menu command File -> Quit; we then are given the opportunity do write a restart file (cf. Restart).

The program might also be exited in the "general windowy'' manner, by left-clicking the cross in the upper right corner of the program window or by using the keyboard shortcut Alt+F4. Such closing of the program does not cause the writing of a restart file.
