No.  What you see is the same I see on Windows 7 and 10.  When I said
that the key "does not toggle the setting", I was referring to the
final outcome.  But the LED indeed blinks.

But as I said, from a Windows 2003 server[1], the scroll-lock key
_does_ toggle the key.  Hence the inconsistency.

remote desktop, from my local windows 7 system.
