R64: Parallax and overlapping/collision

I found that when two instances are in different layers with different parallax settings collision detection will start behaving in a strange way. Objects do not appear to be detected as overlapping according to how you actually see them but in another way. This .capx demonstrates it.

Ya, I'm finding the same thing. Its causing me a massive headache! I need an object to follow the screen but still collide. augh! ...can't pin it to character because they change, and don't always stay centered... can't pin to something on my HUD because it doesn't work. There must be some way around this. Argh... off to search the forums.
