I've been using this for a long time, it's a superb little thing that has to be used for a while before you realise just how cool it is. Its solid as a rock, no stability issues or weird side effects that I've ever come across. I like the way you can add sounds, if you pick really subtle ones it can really enhance the attach and detach effect.
I modified a sample of an electric car window going up and down, so you get a dull muffled clunk and a slight twist of leather as you put windows together and a reversed sample when pulling windows apart. Sounds better than it reads lol I never seem to come across any really useful and bearable in the long term sound packs for windows/program events, always have to end up making my own.
