Before I go down the black hole of troubleshooting does anyone have any pointers for this kinda issue? See the attached screenshot, it's the only screenshot I managed to get. It's happened a few times today, a restart puts it right but...I can provide more info but just wondered if this is enough to get an idea of what is up. It's a new one for me. Thanks in advance. --- Post Merged, Apr 12, 2017 --- A couple more, it's happened again.
