One or more of these photos has been changed in an external application. Should Lightroom overwrite the settings on disk?" WTF. The only program I have open is LR. This type of message drives me nuts. It might be interpreted as: "one or more (400!) photos may lose the edits you just took 3 hours to make

Hi Sean,

This dialog is designed to warn you when there's a metadata conflict of some kind. For example, if you'd edited a photo in Adobe Camera Raw, behind Lightroom's back, and then launched Lightroom, Lightroom would say to itself, "Hmm, the settings that I have on record in my database for this file, and the settings in the file itself, are different. I wonder which are the correct settings?" Then it will ask you, via this dialog.

Unfortunately, Lightroom will sometimes throw this warning erroneously, it sounds like that's what's happening for you. That's a bug we'd just love to fix. Actually, it's not so much a bug as a mole (we whack it one place, it pops up in another). :-)

In the meantime, if you're confident that the photos in Lightroom are the way you want them, and you did not do any edits to them in any other software, then just choose to have Lightroom overwrite the settings on disk, and all will be well.
