i can now edit only 50% of my custom picklists. I have had this problem all day, and except for one Picklist, once they "break" they stay broken. Broken is defined as when i try to open the picklist, i am sent back to the mast Picklists list. One picklist has gone from working to broken. the other three have always been broken (meaning i could create them, but that was the last time i saw their contents).
i think i've reported this elsewhere (hopefully it was the Ideas forum), but we need a way to delete Picklists as well as create them.
