@xym Thanks for reporting the issue.

Are you modifying the file in an editor? If so, it may be this issue: https://github.com/go-fsnotify/fsnotify/issues/17

Can you touch a file in Windows (perhaps in PowerShell?).

FYI, development of fsnotify has moved to: https://github.com/go-fsnotify/fsnotify. Though little has changed with the Windows support, so this is sure to still be an issue. 😦
