Thanks to all who suggested solutions for me...

It seems to have been this:  In MAX.CTL, I had two address lines.  
The first was my 4-D point address (I'm not a full node yet).  
The next line was my bossnode's address.

Like this:

 Address 1:17/23.8 1:17/23 (250) 842-6278 Hazelton BC
 Address 1:17/23.0

When I commented out the second address line, Squish was suddenly 
able to find messages that were written in Max.
