Same here, found this post after wasting 2 days on the problem. Grrr.
Does anyone know how to View All documents using the category filter. I need to select categories using radio buttons, I also have the joys of the radio buttons not working correctly in Internet Explorer, but that is another story.
UPDATE. Inspired by the post above I tried to reinstall the server FP3 which failed, however, on restart it now works correctly again.
