I wonder if that text part on the site either makes use of java or if it html-php coded. If java then maybe that is bugged, any more involved mods should know this. I might ask Aarin about this because if so then you might need to reinstall it, only if confirmed ofc.
Other options, either something in your cookies or so that causes this, I would run ccleaner specially the browser related files and clean them up.
I can't really check the source of the bit that is blocked on your part, it is cut off from right clicking.
Maybe a dns flush will help, I'll look into it. Try ccleaner first, I'll take a look around.
