Each time an agent receive or make a call, a pop up window appear at the bottom righ of the screen. From there, the agent can pick the call by pressing answer. For some reason, the pop up window doesn't appear for some agent. I've checked the setting and every one has the same setting. I can't figure out how bring the pop up back again. I have Jabber Version 14.1.1.56904 Build 306904 and I am on Window 10 (business).
