I have encountered a problem with QEMM and Windows.  If I want to load my
Stacker.com device driver (39K) into high memory, I have to use space in
either D000-DFFF or E000-EFFF.  As some of you might know, the page frame
for QEMM must take up 64K of contiguous high memory, usually at E000-EFFF.
Windows, however, seems to crash when the page frame is placed here.  Adding
X=E000-EFFF to my QEMM device line cures this problem, but then there is no
room for the stacker device driver.  Does anyone know why Windows does not
like an E000-EFFF page frame, and if so, how one can use D000-DFFF and cause
Windows to like me having stacker in E000-EFFF.  I have tried adding
EMMExclude=E000-EFFF to my [386enh] section, but this doesn't help.  It seems
that if I try to load anything in the E000-EFFF range (be it QEMM's page
frame or the stacker device driver), Windows crashes upon trying to open
any Windows application.  Thanks in advance for any info, e-mail responses
preferred.

I'll post any relevant repsonses to this newsgroup.

Thanks,
