> I got a message from someone using NTLFN who says his program no longer > crashes once NTLFN is loaded. Another tidbit - this crash only happens if the memory address space is fragmented and dpmi returns a memory block at a lower address than the first allocation. So running multiple programs at once sometimes causes the problem to happen/disappear. So loading ntlfn may put memory in the lower memory block to cause it to be too small for a djgpp 64K sbrk() request - so it goes higher instead of lower.
