When browsing the chipboard I click on a topic link and read the entry. Then I hit the back button, but instead of being back to the updated main page, it takes me to the main page earlier in the day.

I posted a new message this afternoon, and ever since, the browser always takes me back to that time frame in the main menu. Even when I refresh the main page. Everytime I read a message then want to go back to the updated main page it doesn't. Any help would be appreciated. Thanks.
