I don't think the two threads are related; the steps and results are very different.
Does your Move As button just run Copy MOVE AS, or something else?
The screenshot makes me wonder if the button is being double-clicked by mistake? (That can start to happen as mouse buttons wear out, in my experience.)
When does the lock-up happen? After you click OK in one of the double dialogs?
When it freezes, is it just that progress dialog that isn't making any progress, or the whole program? Can you move the dialog around the screen, and open other Opus windows?
Please make a manually generated crash dump while the freeze is happening. That might allow us to see which code is involved.
