Oh So Slow

I’ve got a thousand slides I’m editing and changing transitions, I’m now 400 in and to delete or move a slide now takes several minutes, I’m using A Mac Pro with plenty of ram, It all started so well too, any ideas out there why it’s now so slow???

Are these images larger than necessary? Especially when it comes to large show, the amount of data gets even huger that one thinks. Double the resolution is four times more data. So it might help to resize your images a bit before using them in FotoMagico.
