Posting Keeps Taking Back to Login Screen

I just upgraded from 2.6.1 to 2.6.2. I’m using the Prologue theme that the WP guys developed for a small microblogging site.

I’m no longer able to post from the Prologue box on the homepage, however, I can post from the normal Write tab. Everytime I post from the homepage, it takes me back to the login screen.

I’ve cleared my cache, tried it in Firefox, IE, Chrome, Safari and Opera all with no luck. I’ve also gone into the config file and added the secret key values and re-cleared my cache.
