Safari not loading some pages

I have a weird problem with Safari that has been bugging me. At seemingly random times it doesn't load a page. Usually it is the second page of a website I visit. This means that the homepage (http://www.cnn.com for example) loads fine. But when I click on a link on the page (to go to sports or politics), it starts loading and then does nothing. Like this:



The New York Times often doesn't load at all. I have no problems at all with some other sites, like wikipedia or Macrumors. Firefox and Camino do not have these problems.

The problem started when I was still running Tiger and Safari 2 on my MacBook. I since started using a MacBook Pro and moved all my data and settings with the Migration Assistant. The MacBook Pro runs Leopard, but Safari 3.0 has exactly the same problem as Safari 2 had on my Macbook. I tried the following:

- repair permissions
- removed all cookies and set my preferences to accept all cookies
- cleared cache
- manually removed the .plist-files for Safari from the Library

All to no avail. When I log in using the built-in Guest Account on my MacBook Pro, Safari runs fine.

Any suggestions are very welcome, as I really like Safari. I prefer it over both Firefox and Camino.

I tried reset, but the problem persists. Yes, Firefox runs fine, as do all other browsers. Safari also runs fine when logged in with the Guest Account.
