I just tried copying in Chrome and it worked. I'm not sure what you mean by 'it did nothing' - did the highlighted text just remain highlighted or did the highlight disappear as it would if it had been copied?
As to the second issue, the paste popup remains on screen for a couple of seconds - are you taking your time deciding whether you want to click paste or clipboard?
If your paste popup is lasting the same duration as mine I would advise being a bit quicker
