I am not sure it is bug or not supported in Windows 7 machine. When i tried in my Windows 7 machine it didnt work though. Then i surfed internet and many people were mentioning it is not supported in Windows 7 and works well in iMac.
Inroder to get object properties you can also try uiautomatorviewer, which is available in AndroidSDK\Tools\uiautomatorviewer.bat.
Let me know how did you accessed these objects in Windows 7 earlier? you were using inspector?
