- yes it is because of windows dpmi.
- no you cannot force your program to use cwsdpmi under windows
- you should create a custom pif file for your program with the dpmi 
  memory set to 65536 by editing the properties. (you need to type
that   in.) this should be professional and allow you program to use the
max 
  possible dpmi memory under windows.)
- note that even though your program might report 16 Mb remaining  
physical memory, i don't think that really is not actual physical 
  memory. AFAIK it is the room remaining in the virtual address space 
  your program's physical memory is mapped into.
