I created a new slideshow and can save as “Slideshow Document” (.ssd) any more. Did you discard saving in .ssd?
Of course not. It is still possible to save as Slideshow Document (.ssp) if you create a new slideshow which only uses one audio track and only uses images for slides. If you using FotoMagico 3 only features like adding a movie slide or using more than one audio track, saving as “Slideshow Document” won’t be avaialable any more because this slideshow doesn’t support those new features.
