I'm doing a site, with header, 3 columns and footer. I did just have the footer in the content/center column, but came across the sitepoint newsletter about how to do a 100% width footer with Crossbrowser.com's scripts. Cool..
Works great.. except I'm having a problem with lots of white space added after the footer. I saw a previous thread about the mm_preloadimage problem.. I removed my preloads, etc., but had no effect. If I remove the "xAddListener" function, .. it works fine.
