I am running version 4.6 on a Macbook Pro with OS X 10.6.2
When you have the single photo and are scrolling through them, I do not have the zoom or crop features. I am sure it is just a setting someplace but do not know where it is.
Also, what are the best setting for this to run quickly? I have a core 2 duo and 4 gb ram.
Thanks Larz
