love reflow far, going great product! i noticed weird behavior when previewing pages. @ browser widths content blocks shift unpredictably. in case 6 column paragraph of text spontaneously "popping" next row. pull browser out hair, , returns correct position. pull out little more... , "pop", down goes. happening without break points set. it seems related css accuracy of width , margin settings reflow generates. these numbers expressed out 14(!) decimal places. if edit resulting css, , reduce them 2 places, problem dissapears. could me, thought i'd share. thanks comment. issue seeing common floating fluid layouts. problem how browsers round number pixles figure out if there space fit last element on current line or not. general fix sub-pixel rendering increases accuracy browser rounds problem happens less used to, still happens noticed. can read more general problem at http://blogs.msdn.com/b/ie/archive/2012/02/17/sub-pixel...
