Yes, same issue here. Win8 on an Asus Zenbook UX31A Touch, purchased with Win8 loaded.
Cut/copy/paste is amazingly frustrating, sometimes it works, most of the time I have to repeat the operation to make it work. Every time I want to throw the machine across the room... between that and the touchpad issues I wish I bought a different machine.
UPDATE: I disabled the send to bluetooth com+ app and cut/copy/paste works reliably now. Thanks for a great tip.
