-selected from the KSM home: "koreader additions > start nickel koreader switch"
did,nickle started automatically

-select in nickel the png file switchtokoreader in order to call koreader
Opened "books", saw the png, didn't select anything, went back to menu right away.

-select in koreader exit (house icon) in order to call nickel
(switch between the two applications as often as you like)
did, went back to menu instead of switching

- finally select in nickel the png file exit_nickel in order to return to KSM
selected "start nickle", started but flashed screen, desktop display order changed, opened "books", had to go to the last page of book list to find the png, nothing selected, went back to menu automatically
then nickle started again automatically, screen flashes "processing content... complete" notice - probably quickly re-indexed the books.
If I quickly click the exit, it didn't response either and one second later went to menu automatically - 5 second later - nickle automatically started again.
