Hi all

@Paul,
Why don't you open the ticket yourself? You have all the skills to do it. The technical description that you made of this issue is more than correct with a detailed way to reproduce the issue. And your English, as written in your messages, is also correct.
If something else is blocking you, just let us know and we can help, here or in GitHub once the ticket is opened.

@Gene:
A common consequence of an error occurring in the GUI is that the GUI may not work as expected in the future. For example if you add the following steps to Paul's steps:
- close the input gesture window
- open a new input gesture window
- open a new input gesture window
- open a new input gesture window
- open a new input gesture window
- open a new input gesture window
- open a new input gesture window

You will end up with many input gesture window opened, whereas the standard behaviour of NVDA is to re-focus the input gesture window if it is already opened in the background.

Cheers,

Cyrille
