In a new install of Windows 10, every 10 seconds the bell rings in Emacs, and the message "<noname> is undefined" is printed. It only happens when focus is on the Emacs window. This makes Emacs completely unusable.

This is not a new thing - I have seen it before on Vista, Win 7, and another Windows 10 system. I've never been able to figure out what is going on - instead I've just installed XEmacs and used that.

However, I just built a new system and figured I'd give it another try - the problem is still there. The only other reference to this problem that I could find is at:

https://stackoverflow.com/questions/47069309/on-launch-emacs-makes-ding-sound-and-displays-noname-is-undefined-message

That posting seems to associate this issue with DishAnywhere.

Well, I'm not using DishAnywhere, but I am using the SlingPlayer app, which is an ancestor of the DishAnywhere app. It just so happens that I had SlingPlayer running at the time I brought Emacs up (I run SlingPlayer pretty much all the time on my system.). When it is running, and I have focus on the Emacs window, the problem occurs.

As far as I can tell, I see no problems when running SlingPlayer with any other applications, including XEmacs. Only Gnu Emacs. There appears to be some resource that both are using which causes this. I was thinking - is it possible this has something to do with the emacs server/client stuff? If so, is there a potential workaround I could try? I really don't know how to chase this down more...

Thanks for taking a look at this.
