I have a problem with PSP hard-freezes (hard reboot = battery out/in to recover) about 50-75% of the times that I exit a HB application (also eboot psx games and ISO games).
Doesn't matter if I use a function inside the program called "Exit" or "Quit" or whatever or if I quit with Home function, both causes freeze.
Also with some homebrew, the application freezes under usage. Programs like GPS-viewers freeze after max 5 minutes, usually.

It's important for me that I have a stable HB-enabled PSP for my hiking trips :-) so I would appreciate all related tips.
Like maybe a suggestion of a more stable version... I'm currently using 6.39 ME-4 on psp-1001 TA-082 board.
(how about OFW1.5?)
