Did you see the bit about the Paste command (via the Quick Access Toolbar) not working either ?

It isn't only the CTRL V that doesn't work, it is also the command button (which is greyed out).

I am grateful that opening the clipboard and pasting from there works, or I wouldn't be able to paste at all.

As I mentioned, after I have pasted something from the clipboard, CTRL V does work (as does the command button). Sadly, having pasted something I don't usually want to paste it again.

This is one of the oddest bugs I've ever come across !
