[VM] vm-postponed-value is nil

[Dave Webb]

trying to get vm running on a windows7 box w/ emacs23.3.1, trying to 
load vm-mode i get the following emacs-lisp error:

 Symbol's value as variable is void: vm-postponed-folder
from past fiddling, i know that this is often missing quote marks or 
parens, but I can't find where this is coming from. I have created a .vm 
file to hold most values, but this string is not present there.
