I used the saved game (bookmark 4) from the forums to get over the stuck game of Gromit in town. We've taken care of the bees and rescued Ms Flitt, now the queen has grabbed Wallace, and Gromit is following her in the truck. But there are no hot spots anywhere to click on (Tab, which normally shows hotspots, show none). I've tried clicking everywhere, but the queen keeps flying and Gromit keeps driving. None of the items in Gromit's possession (some cheese, record, remote) do anything either. Seems stuck in an endless loop.
