How to prevent previously made alterations from loading?

[Quubee]

Let's say I open a bunch of images and make some color corrections, cropping etc. Then I save the joblist. Then, maybe a few days later, I decide that a couple of those images need to be reprocessed, maybe for some other use. So I open them from the original files. I do NOT load the saved joblist. Surprisingly, Silverfast 8 HDR Studio also loads the previously made alterations. I guess it was designed to function like that, but why? How do I prevent it? I often use generic filenames when scanning and when I open the scans in HDR Studio, I get some totally incorrect alterations just because the filename happens to be the same.

Dear customer,

This is the intended normal behaviour for SilverFast.
This allows users to stop working on a project and continue when they start SilverFast again.

Kind regards,
Arne Ketelhohn.
