I don't see why not ? If CWSDPMI implements the same services as QDPMI
(i.e., the DPMI 0.9 spec for use by any application asking for DPMI), then
I cannot see any problems in replacing one with the other.

  Funny thing is, I thought QDPMI used to work?

Never has worked reliably for me. Fortunately, I have very little use for
DPMI, but of course that will change with DJGPP v2.

No. QEMM/QDPMI effectively disables itself when Windows start up, leaving
all memory management to Windows itself. While inside MS-Win, Windows
procides the DPMI services, even with QDPMI loaded.
