Hi Semyon,
Is it possible for you to provide us with the tested application or another similar application with which the problem can be reproduced? If it is possible, please contact us via our Contact Support form (
http://www.automatedqa.com/support/message) regarding this. As an alternative, you can provide us with XAML code of the problematic window so we can check how the window in question should be recognized.
Could you please provide us with access to the tested web application?
BTW, can the problems be reproduced on another machine?
