The problem with this is that people are not all the same. Of course, if they were we wouldn't need computer-human intefaces, as we'd be computers ourselves.

The result is that what seems obvious and intuitive to one person seems baffling to another: that can be down to culture, experience or just the plain orneriness of human nature.

I'm sorry to hear you are struggling with something that seems not to be straightforward. The most annoying thing is that it almost certainly seemed perfectly intuitive to the person who created it like that.

In an ideal world, all software (and hardware, for that matter) would be tested on a large number of people for 'obviousness of UI'. But even in that situation, you might still occasionally find youself in the minority for whom it isn't obvious at all.

I can recommend a deep breath and a nice cup of tea - the ability to wrestle with software that thinks differently from you is inversely proportionate to adrenaline and temper levels.
