[Elecraft] Missing first piece of dash or dot when sending CW with K3S USB input with Wintest.

[VA2EW]

Hi all,

Last WE during the IARU HF I have tested the use of the USB input of the 
K3S in replacement of a RIGEXPERT TI-5 box.

Everything looked great until I experimented that sometimes randomly the 
beginning of the first dash or dot was missing when sending CW via 
Wintest under Windows 10.

I guess it is a real-time related problem with USB under Windows.

Is there someone who have a solution to fix that or must I come back to 
the RIGEXPERT or eventually add a Winkeyer ?
