can't email in iphoto network not connected
I'm using iPhoto '11, version 9.1.5. When I use the "share" button at the lower right corner of the screen, it tells me I'm not connected to network. But everywhere else, I'm connected. I ran Network diagnostics, and I am connected via my Airport. Why and I getting this message, and how can I connect?
iMac, Mac OS X (10.6.2)
