A friend periodically places full-perm textures in an object that she owns to which she has given me modify rights. The object is not locked. My active group is the same as the object's group. Her intention is that I be able to take copies of the textures. It worked perfectly for a long time, but for the last several months I cannot take copies. I can open the content tab of the edit window and try to drag a copy to my inventory, and it fails. I can open the texture, and the Copy to Inventory button is available (not grayed out). When I click it the texture closes and no copy appears in my inventory.

Since I can open the texture, I can easily copy it by capturing a copy from my screen, so there is no security advantage to my being unable to copy it. In addition, since this used to work, I think it is unintended behavior. I cannot imagine a use case in which someone would want to give mod rights to someone else but wouldn't want them copying full perm contents of unlocked objects.
