Trying to limit field access throuhg workflow

I have to admit that the part where you say "and the visible selection in the dropdown is returned to "A"." surprises me. As far as I know there is no code to set that value back and I'd say it will stay put on "B".
If this does happen it will only be on a picklist.... In any case I'll try to find some time to test it and get back to you.
