Would a new user know that there is supposed to be a menu? Why would they click the glowing orange box? Why even think it's clickable? Why is it glowing? Is that normal? They'll think: it doesn't seem to be related to what I'm looking for, so I'll keep looking elsewhere. One thing that I have always noticed to be true (and frustrating) is that new users try to do as little as possible. They try to stay as safe as possible. They want to do one thing, and once they find a solution - any solution - that works, that's what they keep doing. They don't click on strange icons or try new things just because they can. They don't explore because they don't understand, and in my experience they usually think that something will go wrong and they will break the computer if they click somewhere they aren't supposed to. It's hard for us to imagine someone going in with no prior knowledge of how a program is supposed to behave. We have certain minimum expectations, (e.g. there should be a menu bar somewhere in the top left of the screen) and knowledge (you can't do much of anything without clicking the mouse) that they lack that makes what is painfully obvious to us confusing and unintuitive to them.
