It appears that some people have this and some don't.  What I get are 
six pixels in various shades of gray in the upper left corner and then 
the 7th and 8th pixels down the left side of the entire picture are too 
dark.  I don't know what it is, but my image is definitely not shifted 
by six pixels.  Has anyone checked the output of the Windows program?  
Do they just mask it, or is this some sort of timing artifact that 
needs to be covered?

Either way, I've got the problem here, too, so I'll try to fix it when 
I have time.
