You don't have permission to access /cms/index.php on this server.

I'm using the latest stable version of CMSMS and IE7, when I click on a menu-link sometimes I get the following error: "You don't have permission to access /cms/index.php on this server." When I use "Enter" at the end of the address bar it loads correctly again. I can provide you with a link to the website if this problem doesn't ring a bell.

In my template:
{menu template='simple_navigation.tpl' collapse='1'}
