[Spice-devel] Can not drag-drop or copy-paste between guest and host

[Ahmad Ismail]

Just to be clear, copy-paste text between guest and host works. drag and
drop text between guest and host does not work. In the case of files,
neither copy-paste nor drag and drop work.

*Thanks and Best Regards,Ahmad Ismail*
