Users should not be given the impression that they can modify these items. This still does not solve the issue where library items cannot be dragged into prims or user inventory any time after they are initially seen. Curiously, manually copying and pasting still appears to work. On the surface, this seems to have something to do with library item caching on the client, since deleting the cache allows drag to work again once Not sure what the exact problem is.
