Moshidraw is a very 'buggy' program. It conflicts with
other programs, and I often have to re-install it.
It works, however, under Windows XP.
But I just tried to get it to work on a Windows Vista system and it is
giving me the Data Conversion error. If you have solved this problem,
already, please let me know. Otherwise, when I solve it, I will post my
answer here.
