Qemm troubles

Every so often, when running qemm and any program which makes extensive
use of the extended/expanded memory it provides, my pc will get an interrupt
13 (general exception), usually in the middle of running a command.  Most
recently, it likes to occur when running Borland c++'s integrated environment
and attempting to compile something.  I have seen the problem in qemm 4.2 -
the current 5.1x.  The problem would appear to be qemm taking a trap because
the program attempted to reference a word (or double word) at an address that
would require some of the word to be fetched from the top of the segment
and the rest from the bottom of the segment (eg, read a word at 0xffff in
a 64k segment).

The PC is a Wells American 386-25 running qemm 5.1 and msdos 3.3.  A friend
of mine says he has had similar problems on his PC (also a 386-25, but made
by leading technologies, I think).  Anyone know what the problem is, and
how to fix it?  it really gets annoying when you have to reboot the machine
several times an hour...

Thanks, Roger
