Safari/Google Maps issue

Since a couple of updates ago, I've had issues with Google maps in Safari, in particular Street View. When in Street View the map gets 'stuck' on the curser, which stops me spinning the map around. It's kind of hard to explain, but after spinning the map, say, a quarter turn, when I swipe the cursor back over the map it gets stuck to it and swings it back again. Does any of this make any sense? Does it happen to anyone else? Any solutions?
