Hi Jdow,

Just an observation.  This problem occurs on non-linux machines
only?  I could be wrong now, but doesn't Linux cache everything
you read from your hard drive, so you really only read from
the drive once?  Everything opens 4 times faster on my machine
the "second" time I open it.  This would make the multiple read
problem not such a problem, unless the data is constantly
changing?
