== For the last few months, an XP-sp3 machine running IE8 has, on various sites (not all) omitted graphics that show up when I go to those sites using another machine. So far it looks like a minor inconvenience. But this morning, the Google logo on its main page has disappeared -- the largest omission to date. Everything else seems to be working fine.. And Google searches still function as advertised. But what could be causing these graphic omissions?
