Hello, every body. I'm catching trouble with detect instance in another application.

In that form, I can detect ComboBox, TextBox, OptionButton, ..

But I can not detect checkbox, text, input box (which is near ID Au and MK Au) (It's disabled). 

My purpose is enable input box near ID Au and MK Au. Any body can help me throw teamviewer?
