I would have replied by Email but I have a question for the general public.
I saw the same thing (sort of) but it usually occured when using ^P within
Emacs. There was generally no problem until exiting the program and the
system would lock up. I found out later when I bought an NEC P6 printer
(very happy with it, best investment I've made) that this problem occurred
due to the PC trying to write to a non-existant printer and $##*$&^$#*$&
DOS not dealing with it in a civilized manner.  Whenever this happens
now, I just enable the printer and it unlocks the system by generating the
familiar :
	Trying to write to device driver
	Abort, Retry or Ignore:

Of course I have to type "Retry" since anything else will cause whatever
task I am running to abort (Stupid $#%&^&#%#&^#&%^ OS).

My general question is how can I temporarily suspend the ^P function when
entering Emacs. I have source code and if I only know how I would compile
in the change. I am too inflexible to re-bind the previous line key to
anything other than ^P.
