Thanks Tedster. Yup, I'm on NN4.08 (NN has better right-button options for patroling web articles). I agree that it's probably css, which accounts for the webzines having the highest occurrence rate. As I said, I've run afoul of this when trying to inject a remotely served banner and break cache. For NN users, I chose not to break banner cache rather than invoke the full page reload --there was no problem w/ MSIE, I could refresh the iframe only.
