My browser was Chrome. The version was 52.0.2743.116 m.
Tried the updated 53.0.2785.101 m version, but still didn't refresh.
Probably the graphic hardware requirement. Not sure though.
Hmm, yeah 52.0.2743.116 m is the same version of Chrome I was developing on. I'll play around with it and see if I can figure out what's going wrong.
