Actually I think this is a definite bug in the latest NVDA as others on the BCAB list have also complained of this issue.
I too have this issue as described by you since applying the latest update.
Actually what is happening my end is that when I press the Windows key I have now lost all key echo.
So if I press the windows keys and type Word this will start Microsoft Word but there is absolutely no screen or typing feedback from NVDA from the point I press the windows key until Word has loaded.
So the search box is coming up but NVDA is not reporting on this fact or echoing any of the text typed or search suggestions offered.
Keyboard echo elsewhere works normally.
I am using the Windows 10 Essential add on which may perhaps have something to do with it.
Jaws and Narrator are interacting and reporting mormally the Windows key search box fine here so this is a problem specific to NVDA.
Mail for Windows 10
I am using the latest nvda and the latest windows 10. For some reason when I hit the window key the start menu dosen’t come up. I needed to find something but,
I had to use narrator to do it. Is anyone else having this problem? Thanks for any help.Regards, Gary kn4ox
