Problem with Google Analitycs was successfull solved
Yesterday I visited to ovlad.com and saw: page was downloaded fine, but all links were unworked. Firebug (Firefox plugin) helped me. Perpetrator was div id="ga_shade" and problem was with Google Analitycs. Problem appeared after I had seen reports Google Analitycs ([Content] [Site Overlay]) and didn't close window by link "Close", which was at right-up corner. I closed page by system button in Firefox.
First solution, which I found, was very simple - delete cookies with name GASO. Later I found more right solution: must visit Google Analitycs [Content] [Site Overlay] again and close window by link "Close".
