Chris Kirchberg and I were checking our WebEx Event Center connections for a webcast. He pointed out that his new Windows 10 machine showed an outline box when he moved windows on the screen. It looked weird.
JMP webteam developer Peter Jeong shared how to change this and said you may need to restart after changing the settings. Chris tried it and it worked.
