Just started a problem with my mouse not being able to make the program icons come up from the bottom. I thought this was a software issue so I have done everything.. from repair disk to reloaded OSX.. still not working. I also can't get the mission control to open when moving the mouse pointer to the enges, or corners. I just looked at the display console and see that its getting constant error messages. LaunchServices/5123589: unable to lookup core services Also, other messages.. any thoughts?
