Key mapping change?

[Warren Block]

To get some function out of the Windows keys, I use this:

   xmodmap -e "keycode 115 = Left" -e "keycode 116 = Left"

So alt-windows is equivalent to alt-leftarrow, "back" in a browser.  Or 
rather, it was.  It stopped working tonight after a ports update.  Now 
it just does nothing.

Rebuilding xproto, libXi, xorg-server, and xf86-input-* did not help. 
Maybe a genuine regression rather than a dependency problem.
