firstly i do not sure about save and load options work
0.4.3 version have this changes: reading keys from file, enabling abbey odissey fix from console argument, 4 new keys for diagonals, 2 keys for save and load(doesn't tested)
so it shouldn't buggy at all(i hope)

Fredook: update gui first, if it's not helped wait new version...
and check permission of key file (/home/opt/psx4m/keys) it should be owned by user and be rw
