Greg,
  I noticed the same problem sending CW to the K3 using my own software,
CQPWIN, and a Winkeyer when using the Winkeyer to assert PTT.  The cure was
adding even a small amount of Winkey keying delay (as little as 10 msec did
the trick).  So if N1MM allows you to do that, you might investigate it.
Also, using the Winkeyer does allow one to avoid having another line for
PTT.  And with modern laptops there is an advantage that you can use it
directly attached to a USB port without any serial port converters needed
(the Winkey software generates a virtual serial port that the computer
uses).
