Bill Somerville 080f7ef1a2 Make mutable static variables instance variables where necessary
Static storage variables that should  have been class members are made
so. This  ensures that  if they  are used  as initialization  one time
switches   then  they   will  operate   correctly  when   their  class
instantiated more than once. This now happoens for most classes due to
the configurations  switching facility which destroys  all windows and
re-instantiates them.
