Let me start off by saying, I'm new to the world of mac. I bought my first iMac in October. I have a 20" 2.8 with 4 g of ram. Last night I was using Safari 4.0 with logmein to access my computer at work. The screen suddenly froze up, everything went white. I ended up restarting my computer. Everything works perfectly now except Safari. It will start up but then I have the spinning beach ball until I force quit the application. I trashed the safari application and reinstalled it from my downloads folder, but still have the same problem. All other applications that use the internet connection or my wifi connection work. Any ideas?
