Hi, thanks for your reponse. Trying the -m option still gives me the:

Can't locate object method "copy" via package "Math::BigFloat" (perhap
+s you forgot to load "Math::BigFloat"?) at C:/Perl/site/lib/Math/Numb
+erCruncher.pm line 33.
Compilation failed in require.
BEGIN failed--compilation aborted.

The modules I'm using are:

• Perl 5.6.1 (ActivePerl build 633)
• Math::BigFloat 1.38
• Math::NumberCruncher 5.00
• Windows XP SP1 (5.1 Build 2600)
  

Perhaps I should find the older version of Math::BigFloat on CPAN and see if that changes things. I'll let you know what happens.
