To all, I just confirm that Mike is right, this functionality seems to be present in C3D 2008 regardless of startup files. The acad2008 and acad2008doc lisp routines have no mention of vtenable, so it's not getting set there. I have several stations that are installed "out of the box" and the open command resets vtenable every time.
