Whenever I request a webpage on Safari, the application hangs. I am currently using the beta of Safari 4. Although the "Top sites" page loads up fine, with no obvious problems, as soon as I attempt to get to a website the application hangs. This also happens on Safari 3. Strangely, Safari 4 is still able to load the previews of the pages on the "Top sites" page fine. Firefox is also able to function normally. The problem does not exist on other user accounts. Is there anything I can do to try and isolate the problem at this stage? Any help would be really appreciated. Thanks.
