Note that the offending value is blank, so it looks like you aren't doing anything by deleting the value, but go ahead and delete it anyway. (Delete the value, not the key.)
The other amusing thing I learned about this is that a worker thread is created to play the beep sound and the worker thread is created with the priority Time Critical. There are a lot of things that might be time critical, but beeping on a List View change is certainly not one of them. (Yeah, I know, interrupts, blah blah, buffer management, blah, blah. It's still silly.)
