Places function no longer works on iPhoto.
My Mac has OSX 10.6.8 and iPhoto 8.1.2. The Places function no longer works. I can select Places that I used on earlier photos, but it no longer locates new Places on the map. I have read other people's discussions of this problem on the web, but I am not technical and do not understand much of what they say. Any suggestions for a no-technical person would be welcome.
MacBook Pro, Mac OS X (10.5.8)
