Actually, I just ran into the same beach ball issue again (after cleaning up the cache one more time, as you suggested earlier), and this time I did not click on any video files. After launching the app I clicked on a few albums and on one of them the app hung.Thumbnails are shown as empty grey boxes and the larger version of the selected photo is just a black box. Are there any logs I can collect to help better diagnose this?
Thanks,
