Has it ever occured to you that you, more often than not, right click on the desktop window and hit "Refresh"? Te other day, I was at the admissions office at my university, and while glancing to a PC nearby, I could see a person doing this constantly.
I don't know what objective they had, nor what this action seems to achieve except psychological ease, but certainly, it's one thing that irritates the hell outta me! When the computer wants to refresh, it will refresh. Stop putting additional load on it by forcing it to refresh every other second!
There! First quirk on the blog, and first rant of the blog too!
