Build 4001.main.021204-1515 is the first known Longhorn Milestone 4 build. The build itself remains unleaked, however screenshots have been shown by Dr. Nicholas Rush on Yet Another Longhorn Board.
Taskbar/Sidebar explorer glitches can be seen on last two screenshots, looking similar to 37xx builds glitches.
