I'm not sure if RAM is my problem, or just an older Mac that's not too fast anymore.
But when I upgraded to the latest version it's turned out to be so slow that it's completely useless.
I got a discount on the On1 Photoframe (formerly Extensis) and it's much faster and actually useable.
The problem with both of them is organization and overkill on the weird frames. Both of them have huge numbers of really weird frames. Photoframe lets you preview, but you have thousands to look at and I haven't found a way to prioritize by MY criteria yet.
The original Auto Fx gave you a BOOK of the frames, so it was actually much faster to find what you were looking for. Now it's a real pain in the butt.
Photoframe is also less expensive, but both are pretty high, in my opinion.
However, I've got to admit that I really like the idea of them. They're fun to play with. But don't have any illusions there's no way you can take a bad photo and make it better with a cutsie frame. You can, however, take a good photo and make it worse with a frame, even a good one. You really do have to know when to use these products and use them judiciously.
Have fun.
