Yes, this is unfortunately the case and even though Microsoft knows it, 
they won't fix it, ever (go buy Vista was what they told me).  When 
Windows has to fragment SysEx buffers, it removes four bytes and inserts 
two bytes of gibberish, IIRC.  With MIDI-OX you can get around this by 
specifying a large enough MIDI send buffer (one that can hold a complete 
block of sysex).  The other option is to use the Windows Media Player, 
which apparently adjusts the size of the buffer (or uses a large enough 
buffer anyway).
