Not sure what's happening but it's driving me nuts.  The cursor either lags or if it waits, it moves all over on its own. It's like it's completing tasks from before. Then it runs fine and all of a sudden, I can't get it to go anywhere.  Seems to have a life of its own. I've looked at preferences but don't see anything I can alter.  It seems to have just happened on its own.  What can I do?

    You can try doing a PRAM reset. To do this shutdown your MBP. With your lefthand hold down the option+command keys. Power on the MBP, and immediately with your righthand little finger hold down the P key and with your righthand index finger hold down the R key. So you have the option+command keys and the P&R keys held down. Wait until you hear the Apple chime twice, release the keys and let the MBP boot up. Try that and see if it helps. Follow up and let us know if that worked for you.

    Thanks. I will save the reply. Today it's perfect. I wonder what causes this to happen?
