Once I'm in the Directory I can't go to the Calendar

If I browse to the Directory, and then attempt to browse to the calendar (click Tools > Calendar) I just get redirected to the Directory.

If I manually type in the church-calendar into the url it works. If I just wait about a minute, it works. My guess is that the menu is being loaded asynchronously with JS and my browser is not showing this to me in the form of the page loading animation.

What browser are you using? I have no problems with IE8, FF, Safari, and Chrome. I guess your operating system may also have an influence. Mine is Windows XP SP3.

FF5, Windows 7. I'm pretty confident it's the asynchronous loading of the menu in Javascript that intermittently isn't loaded in time for me to click on something. If I wait a few seconds it doesn't happen.
