Indeed. The settings revert as soon as you change programs.
If you want to save that modified Program, you MUST save out the program to
another location on the HD - User/Favourites or whatever . .
Remembering of course that the ROM Programs cannot be modified
to the ROM.
Also remember that if you modify a program that is already HD-Resident,
(Banks you have bought-in for instance) . . . and then SAVE it,
it WILL overwrite the original . . .
So save to a different BANK . . . . .
Then all you have to do is REMEMBER you edited it, and WHERE you saved it
