Problem with Native Modal on Mac

In the Dialog Boxes JuceDemo, if I select 'Use Native Windows',  try the 'Load File Browser', navigate and select an audio file / image, the dialog box hangs forever... : / Works fine in non-native mode.

How can I load audio files using the native mac window?


config: MacBookPro OS 10.10.3, Xcode 6.3.2

Works fine for me..

Where in the code does it actually hang?
