I've just upgraded to iPhoto 09 and am having a problem I didn't used to have on 08.

When I view photos I like to see the full photo onscreen (usually with black bands down either side depending on how I've cropped the photo), i.e. not have the screen filled with a zoomed in version of the photo.

With 09, the screen is filled and when I untick the box in Settings for the slideshow there is no difference. This happens whether I'm viewing it on TV or my MacBook.

Any advice.
