Since when I updated to Mavericks on my MacBook Air I have the following problem. When I open a file on my desktop (especially a TextEdit file) the icons move automatically to the right of the desktop, so every time I have to move back the file in the position I wanted to be. I tried to trash the hide file .DSstore, and the file in the Library/Preferences com.apple.finder.plist and desktop.plist, and restart the computer. I've been trying many times during these days, nothing happened. It's very annoying. Anyone can help me? Many thanks in advance. Can anyone help me?
