Problems with iPhoto
First, trying to edit some photos, when I change the contrast even by one notch, the whole photo turns black, but will go back to normal upon hitting undo. Doesn't happen with all photos, just some of them. Mostly jpegs.
Second, opening some folders/albums, no thumbnails appear, only dotted outlines in replace of them. However, dragging the thumbnail size slider left or right, will make all the thumbnail images appear.
Third, I have been trying to copy my library onto my external, as I have done many times in the past. Only now, it goes about halfway then stops, giving me the message: "iPhoto cannot copy the library because an item named "" already exists".
I have already tried deleting the iphoto.plist file to no effect.
Please help! Why am I having so many problems all of a sudden? I would love to copy the library incase something worse happens, but it won't let me!
