Are you an engineer? I have great respect for engineers in general (Claude Shannon was the greatest), but sometimes they take that attitude. I'm a physicist and when something fixes itself before I figure out what's wrong, it drives me crazy! I can no longer diagnose anything, so I have no idea when or whether the problem will reoccur.
But, as

By the way, how do you cut/paste a member's name so it shows up like it does below our avatars?
