I'm afraid it won't get any better moving to 6.5 (but 4.11 SP9 is
essentially the same as 4.2 anyway <g>). There seems to be something
wrong with QPro and the ODMA stuff on Win2K and greater. As you have
mentioned, you get the "In use" error, but the file actually does get
saved. I've just tried to get used to it.
