I have a series of folders that are shown in red in the folder list, indicating that LR can't view them. The effect is that the folder can't be synchronized and I can't move images into the folder. Other folders in the same list are OK.
I've tried "locating a missing folder" and it re-linked it OK and the folder name turned white; however, when I clicked on that folder again it turned red again. The half dozen folders that are already white, stay white when clicked on - ie they don't get "lost".
Also tried creating a new catalogue from scratch: set up a folder with 2 sub folders, put pictures in each, imported everything OK. The top level folder stayed OK, and allowed images to be moved into it, but the 2 subs turned red.
Also when synchronizing the top level folder, it did not recognise (and import) a new file that I had copied into it using another application.
I'm using Windows Vista Ultimate and version 1.3.1
any help on this much appreciated!
