In the Query Results, you can't copy the value of a cell by left-clicking on the cell and pressing CTRL+C (which is the preferred behavior); however, you can right-click on a cell and choose “Copy” from the context menu.
However, in single record view something strange happens. When I right click the cell and click copy, it empties the clipboard so that nothing is on it, so that is not working; however, when I highlight the full or partial text in a cell and press CTRL+C, the directory path of the currently opened repository is copied to the clipboard, which seems very strange.
