Hi, I've got a clicking noise happening at random on what seems like only low pitched tracks in Vegas. I don't think anything is overloading, and it happens to files that will play fine in Sound Forge. At first I thought it was part of the program not tracking MTC well enough when I'd record some old multi-track minidisc stuff into it two tracks at a time, but it has now just done it to a file that didn't even originate from Vegas- it was a Sound Forge recording, and again a bass track. If I record the same track again (or maybe open the same file again) in parallel, the clicks can be in completely different places. These are files that I haven't even touched yet for editing btw.

Thanks for any clues as to why this is happening.
