Help keyboard shortcuts no longer speak in event list mode

[reaperaccessible]

As mentioned in the text, F12 in event list editor mode no longer speaks on my machine.
I see that the keyboard help is activated since I can no longer change mode or start playback project but nothing is spoken anymore.
On the other hand, I can select the MIDI events in the list and this is correctly stated.
If I press F12 again, everything returns to normal.
But F12 works perfectly in all other modes in the MIDI editor.
I only have this problem on one machine.
I tried to set Reaper to English with the OSARA keymap and I get the same behavior.
I have no idea how to solve this problem.
Someone would have any idea?
Thanks.

Sounds like MSAA is being used to deliver the reports. That being the case, shortcut help won't be able to speak when focus is in a listbox control. Which OS and screen reader is on the effected machine?

[reaperaccessible]

Windows 10 Pro +NVDA last.

Can you go to your REAPER resource path, find this file:
reaper-extstate.ini
Post it or copy the contents here so I can have a look?

Try closing REAPER, then add this line to the OSARA section:
UiaNotificationEvents=2
Now restart REAPER and check whether Shortcut Help reports with focus in the event list.

[reaperaccessible]

Yessssss! you got it.
Is the problem only on my machine or is it an OSARA bug?
Thanks.

[ScottChesworth]

Dunno. I haven't seen it anywhere else yet and our code for reporting hasn't changed in a long time, so I guess it's just gonna be on that machine. If you hear about anyone else with the same situation, please let us know.
