I'm not having any problems viewing the board. Here are the settings I'm using:

Preferences:
List messages posted within the last 2 weeks
List style: Threaded list
Display Style: Single Message
Sort Order: Mixed Order

My display settings are 1280X1024 and 1360X1024 (dual monitor - looks fine on either monitor)

Firefox 3.06

I do allow JavaScript, however I set mine to now allow the scripts to move, resize windows or disable or replace context menus.
