When I loaded elements 11 for mac on my macbook pro I can no longer access my pictures thru iphoto without using the opt/comm click method on the iphoto icon and the iphoto library is now empty and and Adobe has them all. What happened? - Diana
You'll have to describe what's happening in more detail. PSE never automatically imports anything from iphoto unless you told it to. Were you using a referenced iphoto library, by any chance? There is absolutely no way that PSE would empty the iphoto library. Even the "from iPhoto" command makes duplicates, specifically to avoid ever writing into the iphoto library.
Did you ever use File>Open in any program recently and point it to your iphoto library?
