I'm using Lightroom 4 on Windows 7 to manage my photos and videos. I also use it to publish photos and videos to SmugMug. I recently published a video that is about 700 MB in size. Lightroom indicated that the publish failed due to a timeout. However, the publish was in fact successful, because the video now shows up in the gallery on SmugMug and can be viewed from start to finish. But in Lightroom, the video is still listed in the "New Photos to Publish" section of the published collection.
How can I force Lightroom to consider the video as successfully published so that it doesn't try to include it in the next publish of the collection it is in?
