you yourself have the cure.   I have found that DOS drivers (CW keyers
etc) do not run well in any Windows operating system because Windows is
taking up so much of the CPU time.  I have experienced this in other
Logging programs which provide a CW Keying facility.  I have found the
answer is to get out of windows COMPLETELY.

This can be achieved by watching the PC screen and as soon as you see
the message 'LOADING WINDOWS 95' hit the F8 key.
You will then be offered a menu with options;    select Shift/F5.
You will then be in DOS with the c:\windows prompt.
Change Directory to the root directory (where, I assume your SD is)
then load SD as you would do in a non-windows environment and your
computer generated CW should be perfect.

Hope to QSO you in VP5.
