photo stream not updating in iPhoto
Photos that I take on my iPhone 4 are showing up in the Photo Stream on that device and on my iPad but not in iPhoto, at least not for a long time (hours or days). Quitting and restarting iPhoto doesn't help. Yes, Photo Stream is turned on in iPhoto preferences, with automatic uploading enabled. Any clue how to force it to show all my recent photos?
MacBook Pro, Mac OS X (10.7)
