Four years later...
The Steam version of Luxor: Quest for the Afterlife has finally been patched to support the Windows 7 and Windows 8 operating systems.
It's not clear why MumboJumbo (the developers Luxor: Quest for the Afterlife) waited over 4 years after Windows 7 was released to offer a patch for "the #1-selling, action-puzzle game"... but rather late than never, huh?
It's worth noting that the Steam demo for Luxor: Quest for the Afterlife wasn't updated to support Windows 7 and Windows 8. Maybe they'll get around to that in another 4 years...
