Thank you. Now it updates balance correctly when pressing reset, but after first roll it halts giving "unhandled exception" error with the details below: (It does same thing on Win XP fin and Windows 7 UK machines)

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.
