In LR 5.3, when I try to rename a single image I first get the message that LR cannot rename. If I then repeat the process (luckily LR retains the new name in the change box), it works. Gets a bit tedious having to do everything twice. Any suggestions as to what might be causing this? Windows 7 Pro. Thanks.
If you have just switched to this photo then LR is busy reading the photo to compute a preview or check its XMP status, and when a file is in use, it cannot be renamed. If you wait longer, for the loading or three dots to go away from the thumbnail it should work the first time. In other words it works the second time because LR has had enough time to complete everything it was doing with the photo by the time you’ve cleared the error of it not working the first time.
