With Watchman installed on Windows subscribe hangs

[clubside]

I've been having problems with watcher on Windows 10 working for a while then failing to notice changes so I decided to try the Watchman option. I downloaded and installed Watchman, made sure it was on the path and am able to run watchman -v successfully. However after setting this up watcher just hangs at await watcher.subscribe and am forced to close node from the Task Manager as the terminal is locked at this point.
