Sorry, I didn't see the error until now because editing the post didn't bump the topic. That's a scrollbar bug... there are probably several of them that at some point I'll buckle down and fix. It happens when loading new levels, as you said, based (I suspect) on some combination of the layer sizes and scroll positions of the view before loading and the view after loading. I've not deduced the exact cause, though, so if you could find a 100% reliable way of raising that error, that'd be great.


In other news, in keeping with the thread title, I guess I need to start implementing auto scroll into parallax mode...
