Safari is version 0.6 or something like that so except it to have bugs or certain features behave abnormal under certain conditions. If you want something more robust, use netscape 7.2 or mozilla 1.5, most people would say IE, but I dont care and test my site on IE, even considering 90% of browser market is IE. If your site works fine under the latest mozilla, you should be ok.
