Details
Using the following code:
- Load the page and both checkboxes should be checked
- Hit the reload button and the second checkbox will now be unchecked
- Also occurs if you go back to the page after submitting the form
This is a simplified version of a page I'm writing, the main problem for me is
that if a user goes back to the page, their previous selections are lost.

Note - this works under ie.
The code within the if statement is never reached on a page reload to set cb_B
unchecked (using an alert statement to debug).
Also, if the line:
theForm.elements["cb_B"].disabled = !theForm.elements["cb_A"].checked;
is removed, the problem doesn't occur, but the page doesn't function either! :)
Interestingly, the removed line doesn't do anything to set the checked
attribute of cb_B.

I see what you mean in Firefox 1.0, but in either a nightly trunk build of
Firefox or Moz 1.8a6, it works just like it should, so it's already fixed,
somewhere after the stable-but-stale branch of the backend code for 1.0. Next
release should do the right thing, even though that's not much comfort now.
