I downloaded Safari 4 today after it was released, but it's running REALLY slow for me. Especially on pages with a lot of images, and most websites I view have lots of images. It's constantly freezing, I always get that spinning rainbow, etc. I want to go back to Safari 3, but I can't figure out how. The safari4 dmg doesn't come with an uninstaller. And I can't re-download Safari 3 because I have a newer version on my computer. What can I do?
