Hi Jules,
The [NSEvent modifierFlags] method, called in ModifierKeys::getCurrentModifiersRealtime, is not available on osx < 10.6 . For some reason it breaks the popupmenus (and floods the console log). Something like if ([NSEvent respondsToSelector: @selector (modifierFlags)])
NSViewComponentPeer::updateModifiers ([NSEvent modifierFlags]);
fixes it
I’m also getting warnings about the call to [[NSWorkspace sharedWorkspace] typeOfFile: filename error: &error] in juce_mac_FileChooser , [NSWorkspace typeOfFile:error:] is not available on osx 10.4
