No action happening

I have run your example, and I can see my icon when I cmd+tab in mac (yosemite). However, when I cmd+tab to the icon, it does not bring up my browser window to the specified url. Did I miss something?

IIRC, you need to right click the icon, and then click "Open in browser".

If that doesn't work, then I'll need to get access to a Yosemite system to try it out.

Clicking on "My Go App" doesn't do anything, but clicking on open in browser does launch the url. That being said, left clicking on the icon itself doesn't do anything except set the system bar to the name of the app. Seems like that should also open the link.
