Cyrano,
That's a little amusing you've developed a PC OCD. I guess mine is that I read the topics in the same order. If something interupts and I have to click off, I don't feel 'right.'
Yes I think we all have our own little neurotic rituals. If I had a camera following me during the day, it'd be embarrassing to see my rituals broadcast on tv. My worst was when I lived in a second-floor walk-up and had to go up the stairs a certain way--and the stairs were outside where people could see me. I'd have to start over if it wasn't right.
Go Nick Rhodes!
