After the upgrade to PAC 4.5.1 the program was running correctly. Then I tried the option "Use Black & White tray icon" which requires a restart of the program. After that step PAC doesn't show anymore a tray icon even if I unckeck the option just cited. The program is up and running regurarly.
In the pac.yml file I see this options related to the trayicon:
close to tray: ''
minimize to tray: ''
show tray icon: ''
use gui password tray: ''
tray available: ~
After launching the program I don't see the tray icon and the main window because it's configured to start iconified. I need to launch again from the command line to see the main window. If I disable the iconification at startup I can see the window but again not the tray icon.
Moreover I noticed I can't anymore iconify the program.
