I have a Windows 10 1607 wkst that can drag and drop objects only within a folder, that is a file can be dropped into a directory in the same directory as the file. If you drag an object outside of its own directory regardless of local or network drives, the icon gets a red circle with a cross. It's not permissions, you can copy and paste via keyboard or mouse, you just can't drag.
Anyone come across this before? Thanks, jlc
