[PyQt] Issue with menubar on MacOS X 10.9 and 10.10

[Thomas Robitaille]

Hi everyone,

Just to wrap this up, I finally figured out the issue: in most Python
distributions I've used in the past (e.g. MacPorts or the system
Python on MacOS X) python is the same as pythonw. However, it turns
out that this is not the case in the Anaconda Python Distribution.
Therefore, the issues I was seeing were due to the fact I was running
the example script below with 'python' rather than 'pythonw'. So the
botton line is that if you run scripts that use PyQt with Anaconda,
make sure you run them with 'pythonw'!

Cheers,
Tom
