I have a burgundy MB142 MB 144 that's in great shape, but the cap-to-body fit is not snug at all. There's no distinct 'click' feeling when you push the cap onto the body; you can feel a little resistance when the cap seats, but nothing positive. I can't see any cracks in the cap, or any damage anywhere on the pen. I'm also not sure where to look, since I don't know what part of the cap and what part of the pen are supposed to be engaging and providing the 'click', if that makes sense. Any help would be appreciated. Scott
