Has anyone else experienced long-term audio capture just stopping on Vista after running for a few days? I've had this happen with my WavePCI drivers and now with a WaveCyclic driver, but it doesn't happen with WaveRT. It runs for what seems a random period of time, which may be hours, days or even weeks, but then just grinds to a halt, with the application not receiving any more data and, in the case of WavePCI, the driver just not getting any more mappings.
