Hi Tomasz, thank you for that link. I just can't belive it. Making my research (based on opinions of other users - I am not experienced enough to have my own opinion) it appeared that MS is one of the best AT programe. Since "system tester" is found as a one of the most important features in that kind of programme, how aplication which has a tester not working propely can be admitted as one of the best. I also can't believe that they haven't improved it yet. It seems like users noticed that few version of MS ago. That is a big POINT for you - they can't do what you did. Congratulations.
Thanks again for your explanations, it was very helpful for me.
