How can I stop my dock from rearranging the apps by itself?
I just received my iMac from FedEx today and got it all set up, but whenever I try to rearrange the icons on my dock, about 5-10 seconds later they just rearrange themselves randomly or sometimes go back to their previous location before I moved them myself.
I never had these problems with Snow Leopard on my last mac so I'm just wondering if this is a bug or if anybody has a fix for it. I found a suggestion to go to ~Library/Preferences and delete 'com.apple.preferences.plist' but I couldn't find it in that folder or anywhere on my local HD for that matter.
If anyone has any other suggestions it would be greatly appreciated, thanks!
iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
