I do not have unpatched version at hand.

The problem concerns using the WIN key as the META key.  I have this
in my default.el:

(setq w32-alt-is-meta nil               ; Alt be diffrent from Meta
      w32-pass-lwindow-to-system nil    ; do not pass ...
      w32-lwindow-modifier 'meta        ; lwindow acts as Meta
      w32-apps-modifier nil)            ; can now bind [apps]

It works for the first chord; but if I try a second M-chord without
releasing the WIN key in between, the META is ignored.

E.g. the first M-v works as expected (it does scroll-down); but if I
retype v without releasing WIN, I get a v inserted at the point.

* HOW TO REPRODUCE

Start "runemacs -q".  In the *scratch* do
(setq w32-lwindow-modifier 'meta) C-x C-e
Press Win-v Win-v (without releasing the Win key).
Get the expected "Beginning of buffer" message (twice).

So far, so good.  Now we shall spoil it:

(setq w32-pass-lwindow-to-system nil) C-x C-e
Press Win-v Win-v (without releasing the Win key).
Get the expected "Beginning of buffer" message after the first chord,
and a self-inserted `v' after for the second.
