iPhoto '11 Slideshow Fails on rotated display.

in Genius Bar edited January 2014
OS X Lion includes build in rotation controls for displays. I am currently using an external 1080p monitor, and I want to run a slideshow on the screen in vertical orientation.

It doesn't work. The slideshow won't start. The screen flashes and the slideshow stops before it starts.

I tried it on my MacBook Pro's built-in screen, with rotation also active. It also failed, which leads me to believe it's an incompatibility with Lion's screen rotation feature, and not with my particular monitor.

Any ideas? Is this a known issue?

    I am having the exact same problem. Iphoto 11, on Lion, rotated display. The slideshow quits everytime.

    I made a search on the apple knowledge base documentation I think this is a common problem with iPhoto




    The resolution given here says you need to quit and restart your application for it to work but I don't think it will work either. You can give it a try if you wish.
