Typical public-sector service

Although it's improved over the years, here's another bit of craziness from Companies House webfiling:

WebFiling has logged you out as the browser 'Back Button' was used or a button was clicked twice.
Please re-enter your login details below to return to WebFiling.

Of course. When users click a back button, or any button twice, it's because they want to log out. Everyone knows this.
