Attached is the problem I just wrote about: You can see several images that come up when i select the keyword "AIRPLANE" in my catalog. The highlighted one is the only one actually in the folder which I cataloged The others were likely filenames and instances before I made some additions or corrections. I thought FULL "Sync" was supposed to resolve things but it apparently just adds new material but does not remove old material. When opening the "I" window, nothing can be changed and I cannot drag the offending thumbnail to the trash. In the editing window, the trashcan is greyed out and no changes can be made. My Question: How do i get rid of all these old incorrect thumbnails?
