On a random Windows VM I just found, I get even more interesting results:

#(2 14856453 72 1 0 72 0 0)
#(2 14856453 104 0 0 104 0 0)
#(2 14856500 72 2 0 72 0 0)

The character changes. I typed in a lower case 'h', but the VM returns an
upper-case 'H' (72) as the press and release field character, and a lower
case 'h' (104) in the character field.

Why?

And why is the character repeated in the 6th field?

Also, under the Windows VM, modifier key pressed and releases /are/ sent to
the VM.
