Linked page is just one example at pbase.com - it does the same thing for many many different pages there. When you click on a lens at pbase, it will generate a random gallery of pics (call this randGal1). Click on one, and it shows you a larger version. Then click back, and it will bring you back to randGal1. Click, "more", and it will generate a new random gallery (call this randGal2). Click on a pic to view, and then click back. It _should bring you back to randGal2, but Safari 3.0.3 (522.12.1) brings you back to randGal1.
Jeremy, you mention in your report that you observed this behaviour in Safari 3.0.3. I cannot reproduce it in the latest builds of WebKit. Can you please download a nightly build of WebKit from http://nightly.webkit.org/ and verify that it has been fixed since Safari 3.0.3 beta was released?
Thanks Mark for pointing this out - I wasn't aware of the nightly builds. It appears to be fixed in the Sept 19th nightly. I'd imagine "bug testers" who aren't testing the latest version are a pet peeve of developers...
Thanks for verifying that Jeremy. Closing as FIXED.
