As I said at some point earlier in this thread... VST instruments are my main priority - and it seems that the windows sound card/mixer doesn't support 'what you hear'... thanks all, but I'll just stick with what I know works for what I'm doing... I don't expect that at some point the 'what you hear' option will appear for Vista... I have explored all the options and I know what I'm happiest with that works for me
It's probably some really bizarre security thing thats yet to be fathomed out and as Vista is still (technically) a 'baby' then as it grows, develops and matures, something will come along thats of use to my system
