Indeed, same problem here. While I can resize the window, it doesn't 
show the corresponding icon. (I don't use Zooom/2.)

This seems to be a problem with the GLFW library; you may want to file a 
bug report. I glean from Apple's documentation that a a judicious call to

   [window setShowsResizeIndicator:TRUE]

at the time of window creation might solve the problem. Cocoa is always 
a little unpredictable when creating UI elements from scratch.
