Hi,do I assume right, that you use a HP-printer as default-printer on your NT?!
Several programs (Origin, Mathcad,...) suddenly showed similar problems, due to the number-format of the System-settings (using European style with a comma for decimals), when having one of the most recent HP-drivers installed on NT4! I only know of such strange decimal-problems, due to *NT*-drivers from HP, never noticed it on Win9x configurations.
Just change your default-printer to any non-HP and test, if the problem still occurs.
