[xubuntu] Desktop Icons move-annoying

http://ubuntuforums.org – Hi everyone. My desktop icons move around the desktop as if they had a mind of their own. I prefer to keep everything on my desktop, so it has many icons until I clean it up and archive old projects. But, the icons never stay where I put them!! So, I constantly find myself searching through the files on the desktop to locate the ones I need to open because they aren't where I left them.

I also looked through the Settings Manager in various categories that might hold desktop related options, (Hardware)
