Hmmm, I am not really sure. Instead of the "automatically" setting, you can set your browser to check for the newest version of the page "with every visit to the page" by clicking that option instead of "automatically" but if you have an older pc, it might slow down your browsing speed.
Also, do you have LCT set to "show all topics" ? This option is located at the top of any forum right under the button that you click to post a new message.
