Using 116m.  I copied a file path to the clipboard.  Then I put an IQ cell into Edit Mode, and used Ctrl+A to highlight the existing contents.  Then Ctrl+C to paste the new text into the cell.  The Paste Special dialog appeared, asking if I wanted to paste Unicode or HTML format.  I pressed Enter to paste Unicode format.  The highlighted text was not replaced.  Rather the pasted text was prepended to the existing text.  Bug?
