It is just the opposite.  OS/2 runs anytime (how else would you get back to OS/2 from DOS if OS/2 was asleep?) - it is DOS that stops when you switch back to an OS/2 task.

Nope, it's the other way around. All os/2 sessions are always
running. The dos box is ONLY running when you're looking at it.

         I agree, incredibly bad assumption!!  I dont now why I typed
that, but, I do knoe DOS stops not OS/2....  I guess I just hurried that
message.  You Would'nt believe I've been a user since June of
'88?

        YES!!! I KNOW!!...      
        
        This is the only the fifth message (or more) to correct me.
I missed stated myself.....  A slip of the mind!  
        
        Dos shuts down when switched out of the box...  
        Its terrible to make a mistake in this echo <GRIN>....  
        
        Thanks,

        Emmitt, 
                
        Thank you for correcting me!  I do know OS/2 does not shut
down, I meant to say DOS does when you switch back to OS/2...   
        
        Believe me, I wish I was not so hasty when leaving that message.
I have been using OS/2 from 1.0 EE to 1.2.  So, it is understood by
this end how the DOS mode behaves.   I will, in the future not send a
message without reviewing it. Believe me, its a very unforgiving mistake.

Well, I guess the only thing left now is for them to burn you at the stake? (ha ha)

I too had been under the impression that OS/2 stopped when you went into DOS
mode.  I just assumed that they were switching from protected mode (OS/2) to
real mode (DOS) and that they weren't going to go to the trouble to context
switch while you were running in DOS mode.  I checked up on this, and I was
wrong.  They do indeed switch back and forth between real and protected modes
while you are using DOS in real mode, so OS/2 sessions running in protected
mode do get time while you are in DOS mode.  Now the interesting question
is why didn't they do the reverse and switch to real mode while you
have an OS/2 session in the foreground to allow you to run DOS tasks in the
background?  I'm going to guess that the reason is that a DOS program would
directly write to video memory and screw up whatever OS/2 sessions are
currently using the screen.
