I have made a variation using geo.css.
As long as the page shown trackers or forum it is ok.
When it as to diplay a wiki page including another table or td; title, box and even a customized box (align right) all those are mixted (1 cm at least) with the right column.
Text is ok but no boxes as i describe above.
I have played with width and margin on the css on TD#centercolumn and
DIV#tiki-center but i can't do nothing about this problem...
