Hi Eli,

Thanks! You were correct. I found I also had to disable the modifier key combinations as well, so I did:

    (define-key global-map [noname] 'ignore)
    (define-key global-map [C-noname] 'ignore)
    (define-key global-map [M-noname] 'ignore)

Your input that I should have reported this earlier is well taken - then perhaps Emacs could have been updated long ago to simply ignore these nonname pseudo keys by default or a workaround documented.

Again, thanks for reaching back out to me on this!

Best regards,

Rick

This is produced if Emacs receives the 'noname' (VK_NONAME) pseudo-key
key-press event from Windows.  It sounds like DishAnywhere and
SlingPlayer are sending these pseudo-keys to make sure the system
doesn't go to sleep when these applications are active.

Does typing the below inside Emacs make the problem go away?

  M-: (define-key global-map [noname] 'ignore) RET

If you see this since Vista, it would mean you are aware of the
problem for at least 10 years, maybe longer.  I can only say it's a
pity you didn't report this earlier.  Please in the future try to
report problems with smaller delays, thanks in advance.
