Subj:	Re: Warning.  XWATCH/SPY causes crash.

There is a WATCH5 program that came from a year old DECUS tape
that seemed to work fine until DEC introduced FT terminals.
Watching these types of terminals always seemed to crash the system.
My investigations showed that FT terminals use an extended
class vector table (or was it port?) and not all of the table
was being copied/saved/replaced. Increasing that fixed the problem.

However SUPERVISOR has much better functionality so we use that
now.
