}in the DESQview directory on SIMTEL20), it shows 5K of memory allocated.

The system memory displayed in Change a Program is *extra* system memory,
above and beyond that needed to hold the virtual (shadow) screen, interrupt
vectors, DV internal stuff, etc.  The .DVP field includes that overhead.

For an example of a value smaller than 5K, look at the Memory Status .DVP.
With a maximum screen size much less than 80x25, you'll also get a smaller
system memory value.
