Dbl click to copy and paste URLs

Recently installed NIS 2013. All went fine but a couple of days ago I noticed that it takes at least two tries to right click on a URL to copy and paste it into whatever.

If I right click on the URL in the address bar, copy and then go to paste it to whatever, the paste option is grayed out. I have to go back and rt click to copy and then the paste option is there. Sometimes this has to be repeated more than once.

This isn't a big deal, but an annoyance. I looked through the forums but didn't see anything similar. Is there some setting I am missing?
