Bill - FTM takes a while to sort out media items. I haven't tried export branch but if you restore from a backup file you have to access each media item (e.g. by scrolling through them all in the media pane) otherwise they just take forever to display. I think FTM stores the thumbnails in the database to save having to access the media files themselves except when absolutely necessary. Try going to the media pane and scroll through all the items (it can take some time...) then see if that improves what happens elsewhere in the program.
