For some reason "Open Containing Folder" no longer works, whether I select it from the right click menu or hit O. It started before I updated to 0.71 (in fact that is why I updated). I think I had 0.68 before that. I'm running calibre on Vista Home Premium 64 bit. My calibre library is on a networked drive. If I select "Show Book Details" and then click on the link to the folder it opens it fine. Any ideas?
