I currently have Mac OS X 10.6.8 on my Macbook. I update it yesterday and suddenly I've noticed that the System Preferences Icon shows up on my dock. Not only does it show up once, but multiple times (currently 3 System Preferences Icons - but I have seen more of it before I tried restarting my computer). I have tried right-clicking on the icon and selecting "force quit" but it wont work. Also, when I try to simply click on the icon, it DOES NOT pull up the Systems Preferences screen. I try to drag it to the trash can or out of my dock and that doesn't do anything. Also, I see the blue dot below the icon. I'm really scared that my computer is hacked? But clearly somethings not working properly. I'm interested in updating to OS X Lion but I would like to fix this problem first. Please help me out!! Thank YOU so much!
