The OP stated that pywinauto couldn't get at the text, so it's probably drawn directly with GDI methods rather than being a static text control. The accessibility toolkit only works if it's a static text control or the application goes to some lengths to expose the text to screen readers. -- http://mail.python.org/mailman/listinfo/python-list
