Robert thanks for your reply,

it seems you are right, also for other Mac applications the preferences 
dialog disappears behind when the main window is given focus.
Now that behavior is different than the one on Windows, Linux and Mac 
with Qt compiled against the Carbon framework.
Shouldn't Qt library adopt an uniform behavior between multiple platoforms?

Thanks,
