It's become very obvious to us long timers with sonar, that having Asio4all installed is enough to create a great deal of instability if you have proper ASIO drivers for your device.
Of course it's anecdotal but more and more we are hearing of these exact circumstances. When we ask folks to remove Asio4all their systems and Sonar become stable.
