I have added GA to my website and to my Zazzle stores.  I have recently added my IP (got it from ipconfig in a DOS window) as filter, to exclude myself from the monitoring, and added that filter to all my website profiles.  However, yesterday I went to one of my stores which has basically no visits and, unless there is a big coincidence, GA is not excluding myself - I even chekce dif IP had changed, it hasn't.

This particular store in my profile was set as www.zazzle.com.br/store, but I visited its mirror at www.zazzle.com/store.  Could this be the reason? But isn't GA supposed to look at the IP only?

That's why I checked my IP today, it is the same as one week ago and other days I checked it through ipconfig.
