I didn't know that, at the time the upgrade was offered...I assumed (which I will never do again with computer upgrades) that when the upgrade was made public, that it would be a better system to handle my pics/albums, etc...I am not 100% computer savvy and just didn't know...so...having said that, my next (real) question would be this: What reason is there to try and improve an already great I-Photo system with something that was suppose to improve the older program? I'm not the only one who had this problem either...I lost some pics in the transition...My neatly arranged albums and events were messed up...I had to spend hours on the phone trying to get pics and albums back, and I still lost some of them, even with (2) back-up systems in place.
A transition to a "better" upgraded Photos should not allow for the older files to be altered...so....Those who designed "Photo" should please consider what I am trying to say...and to not assume that we all know what to do with upgrades.
