In shiny.go: https://github.com/golang/mobile/blob/master/app/shiny.go
w.Events line 42 throws an error because Events does not exist in the Window interface : https://github.com/golang/exp/blob/master/shiny/screen/screen.go
..\golang.org\x\mobile\app\shiny.go:42: w.Events undefined (type screen.Window has no field or method Events)
This was caught while trying to run the basic mobile example on Windows 10 64 bit.
