Frames, the right way

I love using 4chan on frames. I think it benefits everybody.

The largest caveat is that I'm unable to use the back button on my browser. My question is

1) What's the source of this error?
2) Can this be solved?
3) Why does moot need to do to solve this

5) unrelated but, does anyone archive the text boards?

1) It's not an error. That's how frames work.
2) No.
3) See above.

5) They don't need archived.
