Sorry for mentioning a specific artist. Hadn't thought about that.
Have left LW on all day and all the files are now shared (about 7 hours). I'll leave LW live overnight and boot tomorrow. If LW starts to hash all the tracks once more then I shall think about my options. In truth maybe I shouldn't worry as it doesn't effect my ability to search and download and broadband allows me to leave LW live most of the time. Whilst it may be an issue I guess it's not a big problem so long as it isn't causing a problem for LW.
The chat has been of value and I appreciate the comments. Some of the forums on-line house some people who you might consider peculiar and arrogant if you were to meet them in a bar. Thanks for the support.
