Countdown timer bug

When I start a quiz with a time limit, and time runs out, the JavaScript code simply pops up an alert box. In my opinion, the quiz should be somehow marked completed, and I should be redirected to my results (or if feedback at the end is disabled, then whatever would've happened if I finished normally).

If I try to answer anyway, my attempted answer does make it in (I don't think that should happen). Then the feedback I get depends on whether I'm at the last question:

• If I am at the last question, I am sent to my results, and I can see that my answer made it in.
• If I am not at the last question, it tells me "You have left this quiz partically" (you should really change that message), and the content itself is blanked out.

In that second case, the quiz appears to remain incomplete. If I come back to the quiz (using the url for the quiz itself), it says "Resuming a previous quiz in-progress.", the countdown timer resets, and I'm allowed to continue right from where I was when I ran out of time, except that last question made it in, so I'm actually on the next one (I really don't think that should happen).
