I'm using a MacBook Air from late 2010 or so, and I've recently noticed that my copy/paste abilities have become significantly reduced. Within an app itself it usually works without a hitch, but occasionally if I try to paste between apps (like, say, use a messaging app to send a link to someone), it'll usually either paste the last thing I copied within the app or nothing altogether. Right now, I'm just looking for some kind of quick, lasting fix, as this is making my usual workflow significantly more difficult.
