use case error

Note the error window. It says that is legal when in fact it is a new use case. the legal object is in fact behind the newmUseCase object. There is no way for the user to know that.
test

error screengrab

And then I tried moving the object and one of them; I don't if it was the new one of not, started skitting around the diagram in vague relation to where the cursor was trying to position it! It was actually kind of cute, kind of like a catch me if you can screen game;

Here's the output from what looks like a bug to me.
