/*    This function will get a yes or no answer from a users.  It tries
 * to be smart about how it opens the AutoRequest().
 *
 *    Also you should know that the idea for this code came from the DME
 * function of the same name.  However I have changed it a fair amount,
 * so I don't think there's any problem (mainly I made it smarter about
 * sizing)....
 *
 *    Arguments :  win : a window pointer so that this AutoRequest() appears
 *		   on the right screen.
 *
 *		   text : a character string you would like to appear in
 *		   the AutoRequest.  Be careful that it isn't too long.
