Thanks! I'm just trying to figure out what might be the issue. I thought that it might be the fact I was on 10.3.6 (developer pre-release), but others reporting the problem are on 10.3.5. I don't really use WireTap, but I was curious as to why it had stopped working (apparently, not just for me, but certainly not for everyone) and what the implications might be... Apple closing down recording possibilities? The fact that you both are still able to use it helps rule out some things....
