And how would Mark do this? How do you autoplay on one machine? Alt-Tab from
Windows? Come on.

They obviously don't autoplay. When Fritz 5.32 was released, learning and
tablebases access didn't work when autoplaying. They didn't even notice and a
patch was needed to solve these bugs (I just got the beautiful Dvorak piano
trios for having discovered these bugs; thanks, Matthias). All the autoplayer
bugs in Nimzo 99 and Junior 5 indicate that not much autoplaying at all happened
before release. So 2 out of 3 programs that went to the top in the SSDF list
don't fit with Bob's theory, and several others don't either...
