Wow... just checked it out. They're discussing over on alt.sci.seti. Not a word from any of the "higher ups". Appears they've yanked just the Windows 3.0 GUI executable - including those copies that were on their ftp mirrors.
Some were thinking it was an incomplete restore of a backup, but interestingly, it's only the Windows GUI 3.0. None of the other 3.0s were affected.
