I haven't read through all of the responses yet, but I had something very similar happen to me last Spring with my PSE 5 Organizer. I then downloaded the trial of ACDSee and haven't looked back since. It's lightning fast and it's so easy to drag things over into PSE from it. I LOVE it and wouldn't even consider using anything else.
Ditto for me. I hate the PSE 5 organizer. I used my birthday moolah for ACDSEE pro 2. I love it.. I have been reinstalling all my styles etc on my new PSE 7. It allows me to create thumbnails in new file formats and do many tasks. It is great!
