[PyQt] [Bug] PyQt5 version 5.7.0 OS X.11.4 (El Capitan) MenuBar requires defocus + refocus of app to work

[David Morris]

I have this same issue with PyQt v5.6 on OSX 10.10 (Yosemite).  If I open
my app using python on a command line, menus are not functional until I
switch to another app and switch back.  But if I build an OSX app bundle
(via pyqtdeploy), the menus work perfectly.

I've looked around a bit for the cause of this but never found a solution.
