jw,
Sorry you're running into gremlins, in this and the other post. Not sure what would have changed by deleting the SCLogin module. Really, there's little 'functional' code in that module, most of it's in the component itself.. so deleting and replacing it honestly shouldn't do much. Glad it's working now, cause I wouldn't have really had a great answer.
Hopefully, things smooth out for you, and it's easy sailing from here. If you run into anything else, or have any questions, just let us know!
