iPhoto becomes unresponsive
I recently got a new camera (Nikon D7100) which produces 24-mega pixel images. Now, when I download my images to iPhoto and double-click on an image to view it larger, once I'm in the large view, iPhoto becomes unresponsive. I'll try and click on the arrow to take me back to the collection of photos and nothing happens. If I try and delete the image with the delete key, nothing happens. I have to quit out of iPhoto and relaunch it. Restarting my computer had no effect.
I'm using an older Mac (a 2 x 3 GHZ Dual-=Core Intel Xeon) with 11GB of memory, and I'm running iPhoto 11 (v9.4.3). Is there anything I can do to make iPhoto more responsive short of buying a new computer?
