This will be hard to explain, and may sound a little strange but here goes... Sometimes when I am using a text based program, like Microsoft Word, Outlook or MSN Messenger, words will appear in my text. When this happens I am not touching the keyboard. Most times it is just one word such as....The or there and a few others. I've done a full system scan with my Norton Antivirus and my system is clean. I'm really puzzled with this one.
