Hello, Recently, I'd say within the last 2-3 weeks or so, if I am working in the finder, for example tonight i had a group of files highlighted and i right clicked on them, and then suddenly all of the finder windows that were open (3 of them) closed, and the dock went away and came back and all of my icons on the desktop went away and came back... its as though I force quitted and pressed the "Relaunch Finder" key, but i def. didn't. I also noticed this on my Parents' BRAND NEW iMac. It was happening randomly, just like on my computer. I am wondering if there is a recent update that occured that made this start to happen. Is anyone else experiencing this? Thanks!
