I can make changes to vfs or options, then "Menu > Exit" hfs. When I restart
hfs those changes are still there, not lost. (build 217)
I think, that if I reboot without manually saving new changes first, changes
may be lost, but none the less, I never see a prompt.
Long ago I found that if I make any changes I manually save options and vfs
just to be safe.
Look at your hfs.ini and see if
auto-save-vfs=yes
save-options-on-exit=yes
With hfs open and set the way I want it, I've had to
delete the .ini and manually "Save Options to File", to
write a new ini to cure a problem, at times.
