[Dx4win] DX4Win , Win Keyer with a K3------ settings?

[Bill Barr, N4NX]

I am trying to use a Winkeyer in conjunction with a K3   &  DX4Win.   I have assigned the win keyer to a separate USB port and  it works fine as a stand alone keyer. but as soon as I bring the K3 into play by using a RS-232c to USB interface cable the K3 goes into a key down position.  I used device manager and know exacxtly what USB ports are assigned to both the Winkeyer and the K3.   Anyone offer any setting information or am I just doing something dumb?
