I think this question should be re-posted in the technology section with a note here to say that you have done so. You might also give an indication in Technology that you have re-directed your question from 'How it Works'.
If I remember correctly, I have read that, the sort of problem which you have, can be corrected by clearing-out the Internet Search History in your computer. I am therefore very interested to hear what other folk in the technology section have to say on the matter.
Hans.
