Hi diesel, that is strange about the rockets! I knew they were dodgy on modern hardware but not like that!

Which ACT file are you talking about? There's a few floating around for LB2. You should be able to install any on Windows 7, I mean if it works that's great and if it doesn't then just remove it. You can only have one installed at a time though. However, these fixes are really about stability, not fixing janky colors.
