I have a new Inspiron 1521 with Vista and Microsoft office 2007. I have been having trouble with the curser. If I am on the desk top, the curser moves (by itself) from one shortcut to the other. If I am in outlook, the curser keeps moving from one message or in contacts it will not stop moving from one contact to the other. I end the program and restart the computer. Today I was working in excel 2007 and it was doing the same thing. Going from one line to the other. Any suggestions. I have a separate keyboard and a wireless mouse attached to the notebook.
