So I logged into today to my computer and it wont let me mouse over the dock. I will leave it there for like 15-20 seconds and take it away and it will finally pop up. Also I can use the application switch (Apple+Tab), or the function keys like F11, F12 those. If I hit restart it just hangs forever on the background. I created a new user and none of these problems appear. I really kind of need to use my older user name though. I turned off all things that start up on my old username and still have no luck. Anyone got any idea's on how to fix this?
