Hi folks, Has anyone else had this problem? When in Safari, FaceBook, and either the full screen messages or the 'pop-up' messages, if I try to use the emoji selector on the TouchBar, the TouchBar goes black and unresponsive. Clicking elsewhere on the main screen brings back the TouchBar though. This doesn't happen all the time, but for the last couple of days has been intermittent. I've not noticed it anywhere else on the web, or in any other programs. MacBook Pro with TouchBar (obviously), 15", full custom spec except for 256Gb storage. Windows 10 in Parallels, but problem still occurs with only Safari and Finder active.
