[Elecraft] [K3] K3-WinEQF-Win7 combo question

[Dave, W8OV]

I was able to use the CW keyer in my Win-EQF logging program with a 
WinXP computer by leaving both handshakes OFF in Win-EQF, and setting 
the K3 Config PTT-Key to OFF-dtr.  That computer was recently replaced 
with a Win7 model and am using the KUSB.  [The K3_Utility program works 
fine.]  But I cannot find a combination of handshakes (Win-EQF to K3) 
that works.  I get either nothing, key down, or key up (in Xmit mode). 
Anyone having success keying with this particular combination?
