Suzib: thanks for the research!
I finally had time to read this thread. Suzi, glad the action install instructions made sense and worked for you.
I too miss the photo bin. What I do is put my image I am working on to the right side of the work area. The other images I am using I size down to the size of a thumbnail and place them on the left side.
When I installed CS3 most of the plug-ins I had in PSE5 automatically installed.
