Control key to Copy isn't working right

In the past few days, when I hold down Control and click to make a copy, sometimes it works fine, but most of the time the “+” sign doesn’t appear and I have to click first, then hold down Control and click a second time. This is very frustrating. Is anyone else having this problem?
