I think I may have mis-read your issue. I CAN copy and paste by selecting a vers and then doing a right-click to get a menu.
If I do a File (menu) => Copy / Export verses, and copy to clipboard, this does NOT work. I usually do not use the menu bar items, so I did not see this before. Try the right-click and see if that works.
