I don't understand why the modal dialog boxes don't always appear on top. It must be something simple to do, because you can easyly switch to them as a user. I also don't understand why some windows appear off screen (as the article say).
It is so hard to do the math?
I remember that a while ago I had a problem with Opera e-mail client. I've printed a message and it made no sense. Something was missing. I've compared it with the on screen message and I've discovered half of it was not printed. After that I've experimented with the print settings changing some lengths and with line count of the message and it turned out to be a reproducible bug. I've reported it and it was not fixed in any ulterior version. This is very funny for a page layout application.
