Why does Aperture 3.4.5 freeze when making a slideshow?
I have tried two methods of creating a slideshow:
1. Using the 'play slideshow' option from the File menu.
2. Using the 'new - slideshow' option from the File menu.
In the first case, Aperture simply freezes. The choice of 'theme' (Classic, Ken Burns, etc) does not come up, and nor can anything be selected from the library inspector. The only option was to use Force Quit.
In the second case, a new slideshow is available at the bottom of the library inspector; however, when dragging and dropping pictures, as soon as I try to look in the slideshow folder, Aperture freezes with the 'loading' message (and rotating circle). No pictures can be seen in the slideshow folder. The only option was to use Force Quit.
In both cases, all the photos are less than 3.5 MB, and there were approximately 50 photos in each folder. No music or video was added.
As an aside, I have tried deleting and reinstalling Aperture, and it has not made any difference.
Grateful for any assistance on creating and playing slideshows.
