Hi, for a while now I noticed that when importing photos into Iphoto, sometimes the importing process will hang or take a long time to finish. I would usually have to close Iphoto and import the photos again. My Iphoto Library is about 70GB. I decided to rebuild my Iphoto Library hoping that it would fix those issues. It took several hours to rebuild. Afterwards I opened Iphoto and noticed that when enlarging alot of my photos, there was a blur in the photo before it would display. This mostly occurs with my large sized photos. I never had this before. I decided to import some photos that are already in Iphoto (ones that when enlarged have a blur) from my picture folder. When I enlarged them there was no blur. Should I try rebuilding my Iphoto Library again but this time just select "rebuild all of the photos' thumbnails". I also notice that some of the thumbnails are blurry. Any help is greatly appreciated.
