Subject: GO32 1.11.maint2 and QDPMI 1.04 access violations

    I'm running DESQview/X 2.0beta, QEMM 7.04beta, and QDPMI 1.04.
When I run any GO32 program in a DOS window with protection level set
to 3, I get two successive protection violations with the program
attempting to write to location B000:0000, which is outside of its
memory space.  This does not occur when GO32 is run with no program.
It occurs before the main program as far as I can tell when GO32 is
used to execute a program.  In particular it occurs after the
8024+4096+4096 = 16216 message , but before the prompt indicating the
start of execution of the program, when the ed32-dpmi external
debugger is used.
    Since QDPMI itself gives similar violations (at B000:00B5 and
B000:0054) when invoked from the command line (to turn DPMI off), I
suppose that this has to do with the mechanics of using DPMI.  I would
like confirmation of this guess from someone who knows why GO32 tries
to write to B000:0000.
    Thanks!
