Moreover, iirc we are still supporting build on MacOS X SDK 10.5 and wish to do so for now.</div><div>3. And finally MacOS X Lion which supports "native fullscreen mode" doesn't have possibility to enter fullscreen on other than primary screen (multi-screen fullscreen support appeared in MacOS X Mountain Lion) which is totally unacceptable.</div><div><br></div><div>Taking into account these facts I'd say implementing and maintaining something *only* for MacOS X Mountain Lion is not our way.</div><br><div id="M2Signature"><div>-- </div><div><div><strong><em>With Best Regards,</em></strong></div><div><strong><em>[Oracle/VirtualBox] Sergey Dubov<br></em></strong></div><div><strong><em><br></em></strong></div></div></div></body></html>
