I find this part weird.  Basically how it looks to me is like there's a
chance for the continue button to be clickable, but if you click it then
you cannot continue.  We're currently controlling the sensitivity of the
continue button so it's only clickable if you are allowed to continue.
I don't really like tricking the user like this.
