Thanks, ockham ! Yes, thats a good hint . I'm currently working on a thingy to load poser files from arbitrary locations, or, otherway round, a Win "Send To" which sends stuff to poser. v0.1 will be released the next days. Since this works with python network communication on the local host, my problem is how to shut down the networking sockets gracefully when Poser is closed. Right now, they hang around doing nothing after Poser exit, and it needs quite a while untils the OS kicks them. Thanks again, madz
