Argh ! reposted beacuse my mail server decided to change the 'from adress' ..first post=3Dlost... Hi, reagrding the dicussion of gpsim, linux, windows etc. there's an quite interesting 'solution' to this, being an win-user myself mostly due to work requirments, I'm reluctant to make an dual boot configuration for linux. However there's a linux distro that's called 'Knoppix' ( http://www.knopper.net/knoppix/index-en.html ) that is an *CD-ONLY* solution, i.e. download an iso, burn to cd, put in cd-tray, select 'boot from cd' in bios ( fairly recent bios ), away you go.... Put gpsim on an floppy and you have yourself an 'sandbox' linux to play with. You can have the cake and eat it to..sometimes... :) /Tony -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
