Well, I don't think that a bug only appears for you and mysteriously disappears for the thousands of other A7 users.

Most people apparently have no problem to understand how to work with A7, but some may. However if you don't understand something, the assumption "it's not me but the software is buggy" normally won't get you much further. If you have problems, just ask for help on the forum.

The tutorials were written for absolute beginners, but that does not mean that they are perfect. We're always interested in how to improve the tutorials. So if you found that some important information is hard to understand, missing, wrong or misleading, just inform us, describe your problem precisely and you'll be helped.
