Link to issue number:

Fixes #12605

Summary of the issue:

Restarting NVDA by starting a new instance kills the existing process via WM_QUIT. This exits NVDA by exiting the main loop without exiting NVDA properly. We currently add an event to shutdown properly to the event queue, but the shutdown continues without waiting for that to complete.

Description of how this pull request fixes the issue:

This pumps the event queue before continuing if exiting via WM_QUIT to ensure the shutdown happens properly.

Testing strategy:

Install the PR build for this and try restarting with Ctrl+alt+N. Tested also with subsequent runnvda.bat calls.

Known issues with pull request:
