I think you missed the point, guys.  
The fact that it is POSSIBLE to enter a MODE whereby errors will be ignored
in YOUR program is somewhat orthogonal to the issue of:  what if I want to
leave my machine alone, with all of its programs, alone for a while?

I think what's being asked for is a way, from CLI or workbench, to set
this "pr_Window" field in the process structure for ALL PROCESSES when you
walk away from the machine, and then reset them all when you return.

This, or something equivalent, would let you leave the machine alone and
chug away on many many tasks while you ate dinner or something.  This 
could happen at several stages of a given program, and so asking the DOS
to support it, rather than ALL PROGRAMMERS IN ALL PRODUCTS IN ALL PLACES
where it might be needed is not quite there.

I would suggest a "I'm going away" and "I've come back" menu item somewhere,
that toggles.  Maybe in Project.
