You are right!  I'm using Win98 on the XP2400+ and WinXP on the other one.  More
info!  I have now found that Fruit/Toga have the same problem.  I have also
noticed other quirks about the 256M barrier.  If I set Shredder 9UCI to even
400M it has no problem (In Shredder 9UCI GUI).  In the Fritz 8 GUI Fritz 8 has
no problem but Junior 8/9 acts funny.  When setting the Ram at 256M or higher
with Junior/Hiarcs it shows a little white box saying hash tables were set at
256M but when I click "new game" it shows only half as much hash.  Like if I set
hash at 288M it shows up as 144M.  Does anybody with Windows 98 have this
problem?
