'refresh' goes back to front page

I have setup some wakaba imageboards for some friends.

The problem is that when you navigate to a certain board and 'refresh' the page, you are redirected to the front page instead of staying on the selected board.

I figure it's a 'frames' issue, but can't for the life of me figure it out.

Halp!

Refreshing framesets is cruise control for fail. Just open the board in a separate tab and refresh that. Only idiots would do it any other way.

Why does 4chan allow it then?

I do open boards in separate tabs when I browse but some people choose not to (or are ignorant of how to).
I would like to resolve this problem for people who choose to use frames (or are ignorant of alternatives).

bump?

How fucking hard is this? Frames have been around for fucking years so if you can't get them working maybe you should try digging holes for a living.
