ASIO recording clicks

[MeloManiac]

When I record, at least under XP, I get random clicks in my sound. Sometimes I can record for a minute without clicks, sometimest there are 2-3 clicks in the sound. I tried 6 and 7 ms ULLI (I run 44khz 24-bit). If I could at least MONITOR what I am REALLY recording, so I can hear the clicks when I record - is there any way to do this in Cubase? I have my ASIO outputs running back to the BigMixer/PulsarMixer.
