So an interesting development in this is that after a reboot, I am now
starting to see notification bubbles pop up when the mouse goes AWOL
that say:

Authorization request from 'Microsoft Sculpt Touch Mouse' with a "Check
authorization" button it.  When I click that I get a dialog popping up
that says:

Grant access to '<uuid>'

Device 'Microsoft Sculpt Touch Mouse' (<MAC address>) wants access to
the service '<uuid>'.

With both a Reject and a Grant button as well as an "Always grant
access" checkbox.

Clicking Grant restores the functionality of the mouse and clearly I
could click the Always grant access checkbox to have this automatic.

I just wonder what this functionality is.  I never had it with my
previous Logitech bluetooth mouse.

Cheers,
b.
