Some program settings dont save on exit (iAtkos v7)

hi all,

i just successfully installed iAtkos v7 on my pc, and its probably working very well and i'm happy with it. however it seems like some of my programs are not able to save settings beyond a restart (or maybe its just my unfamiliarness with mac os?).
for example, firefox fails to restore the last session (no matter if i choose to use the built in session management or tabmix plus), terminal fails to use the correct window size i set in preferences (although colors, antialias is set correctly).

does anyone know what might be causing this?

{edit} some more: vlc player doesnt save interface settings, firefox toolbar settings arent saved either.
