Why won't my computer recognize my digital camera? All was right with the world last week, what's the difference today? Of course, this only happens when you specifically want to download the photos so you can create a flyer showing the two sofas you have for sale and you want to do it tonight so you can get copies made tomorrow for posting around town over the weekend when there are a gazillion yard sales going on.
UPDATE: Rebooted with camera connected and all is right in the world now. I'd post a photo of the sofa, but need to get the darn flyer done.
