Missing dock icons in Mavericks
Just a few minutes ago, nothing would load in Finder past when it opens to my home folder. I figured I would try a log out and see if that would fix it. It did, but now my dock is showing missing icons. The app is still there, but only Finder, Calendar, and Trash icons are visible. I can still open the app and the light comes on, but no icon. I restarted and that didn't fix anything. Any ideas?
This literally just happened, and I wasn't doing anything unusual.
