I opened the home.xsp in the notes client and tried to send a file.
It seemed to work, but it happened the same as ray ray below reported: The file was not listed and a short check shows, it was not appended to the file-document at all.
Second problem: it generated a NOTES Link to the file, but did not prepend the NOTES:// identifier, but the HTTP:// one. Obviously, that does not work especially as the Notes Name and the Web Name of this server are totally different, and having the !! separator between Server and database inside the link makes it not working on the web at all
