I just tried using google maps to give me directions, and it isn't working in Safari. Also, when I search for a location, it will go to it, but the bubble that usually has the information is FUBAR. Can anyone else confirm?
My PBs are showing Google Map website without any issues. All of them are now updated to 10.3.9. Maybe you want to uninstall third party plug ins if there is any and try another update download or install the security update 2005-02.
