clay, Steve
     The first thing I did after noticing the effect was to un-tick 
'enable desktop effects'
shortly after installing Lucid, it's been off ever since, I also 
un-ticked 'active window
  glow' in settings>appearance>windows>window decoration>shadows, no cure.
However, touch wood, it seems to be much improved since I upgraded to 
the latest NVIDIA
offering. I did this nvidea upgrade to fix speed problems on 'google 
earth' and seems to
have improved this tailing/shadowing problem as well, so maybe you were 
right about
the graphics driver Clay
  I don't know about setting up a link, but I can send a screen snapshot 
to your personal
email address if it would help, the effect is still there but very much 
reduced.
