Many applications, including Notepad and Wordpad, display their help in an embedded chm viewer; i.e. they don't launch a separate process to view the help. If an MSHTML buffer gets loaded, exiting this chm viewer causes a data execution prevention (DEP) error and the application is then terminated.

Str:

  1. Start Notepad.
  2. Press f1.
  3. Press f6 to move to the content pane. An MSHTML buffer will be loaded.
  4. Press alt+f4.

Results:
NVDA freezes, DEP error and application termination.

Additional info:
This doesn't seem to happen with an older version of the MSHTML buffers. Unfortunately, I can't work out which version I was running at the time.
