For no apparent reason Safari now takes 10 to 25 seconds to change or open a web page on a 10MB Internet connection. The only thing that I know I changed was the install of Office2008. Can't imagine that did the deed, but I can't explain it otherwise. Unplugged the Ethernet cable from my iMAC and plugged it into my Windows Vista HP notebook, and the Internet is fast as ever under Internet Explorer. This is a miserable situation. Any suggestions would be much appreciated.
