Hello, this problem pops up every once in awhile but I notice that (literally) half of my ram is being used when the system is idle,so I go to see whats hogging it..and come up with a process called "find" owned by root.When it is clicked (or right clicked) on to kill a rectangular,empty solid black box appears (which I've never seen before) and the only way to kill it is to use the "kill process" button. Once it's killed everything returns to normal I'm just wondering what exactly this "find" process is and what it belongs to? Thanks
