Thx for the update DerBombo, I'll check with Votan's librray as well to see if this helps.
(Unfortunately I never got this bug so far so I must see how I can reproduce it. Have to read this thread's posts all again
)
EDIT:
I've prepared a version of FCOItemSaver with the libCustomMenu from Votan, you can download it here for testing.
Seems to work normally and I like the thing that the new custom made entries are located below the original ones!
