Kari and others,I've rewritten this system to use a much simpler and more reliable method of monitoring a watched folder, and I think I fixed the problem that was preventing printing on Paul's system. Kari, you should, I think, be able to use it in any folder, but it will warn you the first time if the folder has a lot of files in it. It will also warn you if, when you start it up, it will delete some files already in the folder.
