Me too. I guess without a screen capture of the old width it's impossible to explain, but the board seems definitely "thinner" by about a 100 pixels or so, maybe more.[br]
Looking at the source code briefly, the main table on the front page is set to 100% as it should be to spread it if thats the desired effect. The other pages have hard coded 830pixel widths in them and because it's left aligned you end up with a huge empty space on larger screen resolutions.
