It's really common, in fact I don't know why Apple don't make it open by default.

My dad was getting really pissed off because he was having to save all is files into Documents then move them where he wanted them with the Finder. He was doing this for a nearly a year.

It's not completely obvious what that button is (it's just a triangle), some people (like my dad) are nervous of playing about with stuff they don't know (especially when it comes to file operations)
