Can you do the following please:
- Restart NVDA in debug mode (NVDA+Q, select "restart with debug logging").
- Reproduce the issue (say, press arrow keys while focused on any edit field).
- Provide the debug log (open NVDA log viewer with NVDA+F1, select all, then copy and paste the selected log text as a private email reply to me).
I will then perform some analysis and provide results to the forum afterwards if I notice something.
