Rotating screen landscape and back to portrait freeze my app

running 4.5.0 on IOS and when i turn my phone from portrait to landscape and back to portrait, the app freeze and I can’t do anything, no button working and menu change possible.

Not sure this is related to 4.5.0 as i never tried landsacpe before.

Can anyone confirm if this is a 4.5.0 ios issue or if the would be anything wrong in my project ?

For me it works on both IPad and iPhone
