I have just checked and it works with the NUT 2.6.1-1 package binaries.

However, I noticed 2 important things:
 - the notify command is called only after clicking OK on the upsmon's
dialog box. This is not the expected behavior and I will fix that
immediately. In the mean time you can disable this dialog box by
removing the "WALL" flag of the corresponding NOTIFYFLAG command.

 - the called notify command do not appear on the user's desktop,
neither with a GUI nor with a console. But you can check that it has
been called with Windows' task manager. This happens because the notify
command is called by the user SYSTEM which has no graphical display
available (no desktop). So the notify command should not try to display
information directly. Maybe there is a way to workaround this using
runas but I have not managed to find it yet.

Thanks for your input.

Regards,
Fred
