JS errors on MacOS

[Patrick Klug]

I'm just testing my .nw package on Mac OS and I get inconsistent behavior  Most of the time the app doesn't work and shows some JavaScript error that some objects are not defined.

These errors come through window.onerror which I'm listening to in my app.

What's odd is that the errors are not consistent and sometimes the app runs completely fine without showing an error.

I'm a bit stuck on how I should troubleshoot this. any ideas?
