Thanks for the heads up however I have Symantech Internet protection / AntiVIrus on that machine and they seems to work very well. One of the biggest reasons I upgraded was that there was some sort of conflict between the drivers for the CDRW / CDR and the OS and the bloody thing kept crashing. If that is fixed I will be pleased and if not I will probably buy a CD DVD combo drive.

I did check Sonar and that was working fine !
