Im new to typing so imagine my horror when..........?

Yeah there i was on notepad in vista, just typed my name and address on top right corner, then went across to start with Dear Santa etc and me name started moving as i typed. I thought "hello john, the drugs are working" but they werent to kick in till later, so whats with the spooky goings on then george? Any ideas please? It was nearly as spooky as when i typed Q33NY then changed font size etc and THAT came out of my laptop when i typed same thing again. I still have nightmares to this day. It was all the more freaky when i found out what time i was born. **** it was 9.11. Anyway, help on moving name please. B4 i lose it AGAIN.
