I just built it myself, and this looks pretty good. I can start xterm and urxvt-X wjust fine without a flickering cmd window. However, what does NOT work anymore is to start the X server. I had to start it manually for testing xterm/urxvt. Given that the X server shortcut is just a `run /usr/bin/startxwin.bat', is it possible that the new incarnation doesn't start cmd correctly?
