The new computer had them a few days ago, then they stopped. Came back again late last night, after a delightful Sunday meal -- steaks and big mushrooms grilled over hardwood lump charcoal,* lightly-steamed Brussels sprouts and baked potatoes -- and I must admit, I was too busy digesting to fiddle with it.
But tonight, I think I'd better open this thing up and see what's going on. Backlash in the gear trains? A loose 10's-carrying arm? A stuck steam valve? Something.
* Also hardwood kindling to start the charcoal. Lighter fluid? Pfui! The difference between the good charcoal and the pressed briquettes of my youth is the difference between live music and a scratchy recording.
