I'm not sure if this is related to Vegas Pro 8c or my sound card (MOTU 828MKIII). When I have ripple editing on and I attempt to undo, my sound card starts squealing. Rebooting Vegas makes it stop. Squealing from an 828MKIII was very common when the piece was new, but firmware updates have eliminated the problem (except for this undo issue).

Has anyone else seen this?
