Dennis,
Yes, it appeared to be happening with the Nikon AF-S 18-200mm f/3.5-5.6G VR lens, but not with some others.
As for providing details about the problem, I can empathize. I have a few IT support clients that will just call and complain that their "computer isn't working" or their "phones are having problems". Details seem to elude them. Ironically, most of their issues are typically found to be user errors.
