What are some of your biggest pet peeves amongst your peers and other professionals out there? To start it off for me one of the huge pet peeves is watching someone who really should know better (MCSE and many many years of IT experience for instance) consistently double-clicking where a single click would suffice. Most notable web page links. And then it is even worse when they get confused about it not reacting like it should. Sometimes I'll be nice and point out that it is just a single clicking and not a double, but then just a minute later they're back to double-clicking everything! It drives me batty, though probably the underlying thing is really an irritation about people not learning. I guess that's what you get coming from a family of teachers.

So what are some of the things that really get your goose?
