I have also had problems with Safari slowing down, but I dont think it started with 10.3.6 (which I am still on). It's usually quick and responsive when it's freshly started but after some days of medium use (3? 5?) it slows down and is much less responsive. I notice the small yellow help text boxes are showing up long time after the mouse have left the area, and as I have several bookmarks in my personal bar I must be very careful I don't mouse over them, because then I know Safari will be slow for a short wile. Safari also crashes sometimes, but not often enough to get annoying. And of course - this fixes the above bug, so there's a silver lining to that cloud...:-) / Vicki
