Thanks for the speedy replies.
I'll go and remove all the older stuff (see what happens, lol).
I'm chopping the machine down completely and, once I've transferred all my documents, photo's, etc, will use it as a dedicated internet audio streamer (internet radio station, "squeakstream") running just an operating system and "SAM4 Broadcaster" from
www.spacialaudio.com
Trialling now on
http://s4.secondstreams.com: 8430 (delete the space inbetween the com: and the 84) but need to look into licensing for copyright and performing rights (USA based).
*Might* try streaming video from it too, but not sure it's up to it - only 512mb RAM supporting a 700MB P1 processor.
