Sudden PSAs

For the first time today, I'm getting PSAs on half my sites (the other sites are fine). These are sites that should have plenty of ads available to them. Now here's the extra-special interesting part. These PSAs only show up if I view the site in IE. The real ads show up fine in Netscape. Anyone else seeing this phenomenon?

I've seen somebody else report problems as well and they even said that Google had replied saying that there was some problem in the algo, although I don't know how true that is. In any case, if it continues, just login to your account and use the contact link to report the problem to the big G - they should be able to sort it out.

Can't you just use their filter tool and take out the URL's you don't like? (I only ask because I never use it...

I've never tried filtering out PSA'a but even if it can be done, you'll just get other PSA's, so it won't help much.
