SWITCHER allows me to swap between apps and rejoin where I left off, 
as long as there was not a disk assessing process going on at the 
time.

I've got 496 MB.  Is that enough?  ;)

See above, I have plenty of RAM.

Based on what you are saying, I think that it interfers with the hooks 
that SWITCHER uses and bombs out.  I can use the BW386 but it locks 
up when I try to swap via SWITCHER.

That temds me to believe that 4GW is extraneous...  

 BC> Also read the BWAVE386.VMC for setting MINMEM, MAXMEM & VIRTUALSIZE. 

 BC> I have:

 BC> MINMEM = 512

 BC> MAXMEM = 2048

 BC> VIRTUALSIZE = 2048

Just where are the docs for that located?  Somewhere in there seems 
to be a solution.

Thanks for giving me something to play with!  

I appreciate the info in your response.
