Recently purchased a new Macbook 2.4 (a week ago) to compliment my iMac, and I decided to upload my 20K+ photo's to it so I could have my photo library to work with while I traveled. The problem I am having is this- As soon as I open Iphoto, the faces "working" icon starts turning to show that it is working... on what, I have no idea, since I have not accessed it nor have I asked it to look for any faces (nor do I plan on doing this on my Macbook, that's why I have my iMac). I let it run, and everything seems to run fine at first, but if I let it chug along for more than 30 min. or so, it bogs down my computer and will eventually lock up Iphoto. It does it more quickly if I try to open a folder in iphoto after I've let it run for a while. I kept iphoto open for a few hours hoping it would complete whatever it was trying to do, but it wouldn't end in a few hours of working, and would freeze up iphoto if I tried to do anything in it. I did a search, and didn't find an answer on this forum or on the net. This is a flaw in iPhoto if you ask me, why force it to work when the user doesn't want it to.. nor do I need it to! I have to admit that I am relatively new to Apple, and am surprised that they programmed Iphoto this way... Any help or suggestions would be appreciated.
