I run a 386-33 with 4Mb under QEMM 5.11 and DV 2.31, and disk access
in a window is within 10% of the speed of disk access outside of DV
(about 900Kb/sec and about 960Kb/sec, respectively, without PCKWIK,
and about 5500Kb/sec and 6000Kb/sec, respectively, with a 1Mb PCKWIK
cache -- all measurements made by CoreTest).  So my answer to your
question 2. is that I have not had the problem you describe.

However, I do see a peculiar PCKWIK behaviour in DV.  When PCKWIK is
loaded with the /Q+ switch, which enables return of the prompt before
disk activity is completed, this feature works perfectly, but not in a
DESQview window.  Anybody have an explanation of this?
