Hm, just wanted to check it out for you, and the Main Index looks fine - except that NN still does not display the proper font sizes within the tables, e.g. the Categories are supposed to be bigger - but I got this error when clicking on "Info Booth":

System Error: DBD::mysql::db do failed: You have an error in your SQL syntax near 'AND Rd_Commit = 0 ' at line 5 at w3tfilter.pm line 251.

By the way, this error occurs only for a user that is NOT logged in - after logging in, I did not have this error!

Back to NN6 - it seem on W3T it only makes that line bigger that I mentioned before - in showflat (and probably showthreaded) the cell height is overproportional for the e.g "Info Booth Thread views: 9 [buttons]". Everything else looks okay.
