Duplication Problem!

If I try to duplicate any item in my binder, the action is crashing Scrivener for me.

Well, crashing may be too strong a term. When I right-click-duplicate, Scrivener gives me the swirly icon and says “Not Responding” at the top of the window. This doesn’t stop, or at least it hasn’t for me the times I’ve left it swirling, went and ate a sandwich, and came back.

There’s no randomness to it either. It locks down every time I try to duplicate an item.

Any ideas on what to try or where to look?
