Aw: Overlapping panes
I have the same problem with the style nornia.css, i realized, that the only thing missing in the css was a width value for the DIV#tiki-center definition. If you add here 100% it works fine in IE but breaks in mozilla. so you either remove the padding value and have the widht:100% or you must define the width minus two times of the padding value to get a working result in both browsers.
Or even better define tiki-center with a width of 100% with a margin of 0px and add the padding you need to TD#centercolumn. Then you have the a result working fine in IE and mozilla with the same definitions for sizes like in the original style-sheet.
