Ed,
I'm sure I'm misunderstanding something... and I appreciate your patience.
When I send the output to VAC as I change modes on PowerSDR, the CW Skimmer
waterfall changes. When I change the filters in PowerSDR, then the
waterfall in CW skimmer only shows signals in a narrow band (as wide as the
filter). No matter what mode I select, scrolling up and down the CW Skimmer
waterfall shows a frequency range of about 20 KHz.
It appears that signals above and below the center frequency on PowerSDR are
"reflections" of each other.
When I set up VAC, the only WDM that shows up is "Windows WDM-KS" - should
there be another "Windows WDM" - maybe that's the problem(?)

Hi Mark,
If VAC output is set up properly Skimmer will process the entire
sampled spectrum of 48, 96, or 192khz. There is no need to do any
special filter setup.
The demod audio continues as normal. For example, while I am
processing 96khz of spectrum into Skimmer, I am running PowerSDR with
200hz filters.
Some users are confused because Skimmer only shows 10-12khz of
bandwidth on the waterfall, depending on how tall your display is. If
you look at the spot list, you will see that it is reading stations
in the whole sampled bandwidth. If you scroll up and down, you will
see their callsigns by the waterfall.
Hope this helps. Let me know if you have further problems or
questions.
