Hi, I am having trouble with two aspects of iPhoto. The first is, I cannot seem to grasp how to use the faces function, i have put a box around the faces and labeled them like it says to do in the video tutorial. When I click onto the persons faces folder it does not show any suggested pictures with that particular person in it although i have labeled multiple pictures with their face. My question is, do I have to label a certain amount of photos before iPhoto can get an idea of this persons face and is there any other way I can improve faces. Also the faces bar has a little grey loading symbol by the side of it, this may mean that it is searching for faces, i don't really know! The second being when I attempt to close iPhoto using the red cross, the red turns a darker shade and will not close the application. When I try to close the application using the task bar this also does not close and I therefore have to use the force quit function. Has anyone else experienced this and how do I fix it. I am a new Mac user by the way, i'm still learning how to properly use the OS. Thank you.
