No special little clicks on here, but I think the ones who declined to respond because they weren't on your list thought you were making a click. I don't know.
As for your problem, I frequently have the opposite problem and move away from that guide and get a thin spot. Biggest cure I think is practice practice practice. Are you having this problem is it cutting from disk or from rough cut string? I have more trouble with cutting the disk. Temper plays big part too and too wet I think would cause what you describe before too dry.
