[WriteLog] Voice keyer delay

[Gary AL9A]

I'm using my new Dell laptop with Vista in the ARRL DX contest and am 
experiencing a noticeable lag from the time I press an F key and the when 
the audio file starts playing.  It seems like it's almost a half second or 
so.  I never had this with my old Compaq running XP.  Is there a parameter I 
can tweak somewhere to reduce or eliminate this delay?  An ini file command?
