I expect to copy a tag or udt when holding ctrl-key and dragging with mouse pointer
-Copy is NOT performed
Instead a move is performed -without the expected confirmation dialog
-adopt ms windows explorer behavior
-drag to move
-ctrl+drag to copy
-right-click and drag to get aditional options
(Ctrl+C and Ctrl+V behaves differently on tags and udts.
-adopt behavor from tag. paste a renamed copy of the udt at the same level as the original.
