[Elecraft] Problem with NAP3 and K3

[Shel Sherman]

I am having trouble with the sub-receiver cursor displayed on the NAP3
display. The cursor does not correctly follow the VFO-B dial as it is
turned,but lags or stops while the dial is being turned. My configuration
uses the LP-PAN between the K3 and a n EMU-0204 sound card feeding a 64 bit
Win 7 pc. All other functions on the NAP3 work as expected.
Help will be much appreciated.
