Lightroom 4, photos are dark when in slideshow mode. Therefore, cannot create a slideshow. Cannot move photos from grid to add to another collection. Also cannot change sequence of photos. Have searched multiple times for troubleshooting help online with no resolution available.
Just to clarify my problem with the "dark photos"....when in slideshow mode, photos are dark and state "no photo selected" I've created multiple slideshows and this was never an issue. Just downloaded updates as well for Lightroom 4 and this didn't seem to help either.
