I believe there were some patches to QEMM v6, but they have been removed
from ftp.qdeck.com:pub/qemm/patch and replaced by QEMM v7 patches.  Perhaps
Quarterdeck support or someone on the net would provide them to you?  Or you
could consider updating your QEMM to v7.04.  Can't guarantee that this will
fix your (unspecified) "memory problems", but you will get a more aggressive
memory manager out of the deal.

It sounds like you are trying to load more things high than memmaker can
find space for without the big 64K chunk that "noems" gives you.  You might
try specifying the devicehighs and loadhighs in a different order(or
eliminate some!).

You might use a memory mapper(qemm includes one) to see how memmaker has
utilized your upper DOS memory.  This could provide clues on how to reorder
your devicehighs and loadhighs(or convince you to drop memmaker). 

Both QEMM and 386MAX(Qualitas) are smart about reordering your devicehighs
and loadhighs for you so that this sort of problem doesn't happen.  I have
heard that later versions of Memory Commander from V-Communications(Stevens
Creek, CA) also excels in this regard.
