Hey There — I Too Yahooo and had same problem.
After finding your post — and reading I remembered
I could simply disable the YAHOO Stats plugin
which can be done through your main wordpress
control panel under (plugins) (deactivated yahoo stats) little grey box is now gone —
I had already manually shed the yahoo button images
I don’t mind advertising for yahoo — just want to
have control over if when and where —
You can always go with more advanced Stats Program
(yahoo helpfully recommends one) <yikes!>
Hope This Helps
