Hi Dave,

It sounds like the laptop wanting to go into sleep mode and being stopped the another program was likely related. Have you tried changing your power saver settings to have the monitor not turn off for two hours, to see what happens?

It's interesting that you got a stutter on the output of the SC88 as well. Am I correct in assuming that its audio output was routed through the UR22 before going to your speakers?

Also, do you get the stutters with MME?

Thanks
