I have recently installed 8.6 onto my 5400/120 and everything works fine until shutdown where it often (but curiously not always) hangs or crashes. I have Norton FileSaver 4.03 installed and set to scan the hard disc at shut down so suspect there may be a conflict there. Has anyone else had a similar problem? I am checking the conflict now but any info would save time as I have quite a few 3rd parties installed...
