Virtuoso issue on exceed onDemand

Enable the Shadow Window checkbox and in the Window Name section enter WM_NAME=~Virtuoso
Shadow Window creates a buffer on the
Exceed Connection Server machine, allowing drawing
requests to be handled by the Exceed onDemand
Proxy instead of the Client. Applications such as
Cadence will benefit tremendously by this feature
because of the extensive drawing requests that it
makes, which impose heavy bandwidth demands and
impede performance. When used properly, bandwidth consumption and performance can be greatly
improved.
