I had a similar experience on a 386 machine which "emulated" EMS from extended
memory using a special driver. Apparently DV did not like its brand of EMS
emulation, as I ultimately traced the problem to that. Using quarterdeck's
QEMM-386 the problem disappeared, and I have literally run ten DV windows
at once with no problem of lockups anymore.

Since you did not say that your 2MB board is EMS or EEMS I guessed you might be 
simulating EMS from planar memory. If you're not, the EMS driver _still_ might
be the culprit. DV really requires EEMS to run programs in expanded memory.
your hardware/software memory combination might not be to its liking.
